### SUMMARY

A. Objective

The objective of this study was to determine the acute inhalation toxicity of when administered as a vapor for a single, 4-hour, nose-only exposure to rats.

B. Test Guidelines

The protocol was designed to be in compliance with the Environmental Protection Agency (EPA) Office of Prevention, Pesticides and Toxic Substances (OPPTS) Guideline 870.1300 and the Organisation for Economic Cooperation and Development (OECD) Guidelines for Testing Chemicals, Section 403.

C. Study Design

The acute inhalation toxicity of was evaluated in this 4-hour, single-exposure study in rats. The test substance was administered to 1 group of 5 male and 5 female Crl:CD(SD) albino rats via nose-only exposure as a vapor at a concentration of 102,900 ppm, the highest achievable vapor concentration.

Mortality, clinical observations, body weights and body weight changes were evaluated over a 14-day post-exposure observation period. Necropsies were conducted on all animals.

D. Results

None of the animals died during the exposure or the 14-day post-exposure observation period. Clinical observations immediately following exposure included tremors and rales. There were no toxicologically significant clinical signs during the 14-day post-exposure observation period, and all animals were considered clinically normal by study day 1. There were no remarkable changes in body weight. All animals surpassed their initial (study day 0) body weight by study day 14 and were considered normal. The only macroscopic finding noted during the scheduled necropsy was clear fluid contents in the uterus for 1 female. This macroscopic finding is considered spurious and not related to test material exposure.

E. Conclusions

Based on the results of this study, the LC 50 

### of was greater than 102,900 ppm, the highest achievable vapor concentration, when male and female albino rats were exposed to a vapor of the test substance as a single, 4-hour, nose-only exposure. Acute Inhalation Toxicity Study of in Albino Rats

### EXPERIMENTAL PROCEDURES - MATERIALS AND METHODS

A. Test Substance Identification

The test substance, [ was received from on December 3, 2007, as follows:

Identification No. of Containers

Received Description

1 c ylinder Gross weight: Clear, colorless liquid

Purity and stability data were the responsibility of the sponsor. A Certificate of Analysis is presented in Appendix A. The purity of the test substance was 99.9932%. The test substance was stored at room temperature. A reserve sample of the test substance (approximately 6 g) was collected on December 27, 2007, and stored in the Archives of

B. Exposure Methods

The exposure was conducted using a 7.9-L conventional nose-only exposure system (designed and fabricated by . Animals were restrained in nose-only exposure holding tubes during exposure. Food and water were withheld during the exposure. Exposure atmosphere environmental conditions were recorded at approximately 60-minute intervals during the exposure. An Omega model no. HX94C temperature and humidity transmitter probe (Omega Engineering, Inc., Stamford, Connecticut, U.S.A.) provided monitoring of temperature and percent relative humidity. Oxygen content was measured on January 17, 2008 during the pre-exposure method development phase using a Drager PAC III equipped with a calibrated oxygen sensor (Draeger Safety, Inc., Pittsburgh, Pennsylvania, U.S.A.). The oxygen content was 20.0%.

The time required to attain 99% of the equilibrium concentration (or clearance time for the concentration to decrease from the equilibrium concentration) was calculated by the following

formula:

V × K t 99 

### = F

Where: V = volume of the conventional nose-only exposure system, L K = constant for 99%, 4.60 F = flow rate of air through the chamber, L/minute Acute Inhalation Toxicity Study of in Albino Rats

### The calculated t 99 

### equilibrium time for this study was 1.4 minutes. Prior to the animal exposure, the test substance atmosphere was generated to reach the approximate target concentration as defined by the t 99 

### equilibrium time. The animals were loaded on the nose-only exposure system while the system was running. The start of the 4-hour animal exposure began when the last animal was placed on the system.

C. Test Atmosphere Generation Methods

A vapor atmosphere of the test substance was generated using a system similar to that shown in Figure 1. The system operated as follows: The test substance was metered at a known flow rate by a liquid metering pump (Model QG50, 3/8-inch piston, Fluid Metering Inc., Syosset, New York, U.S.A.) to the top of a glass bead vaporization column (2-inch I.D. × 26-inch length) filled with 6-, 12- and 16-mm glass beads. The bead column was wrapped with an Omega electric heating tape (model no. SRT101-100) controlled using a J-type thermocouple and digital temperature controller set to maintain a temperature of 126-135°C. Using a Coilhose Pneumatics Regulator (model no. 8802K, East Brunswick, New Jersey, U.S.A) and a Linde rotameter-type flowmeter (Union Carbide Corp., Danbury, Connecticut, U.S.A.), compressed air was metered to the bottom of the vaporization column. Vaporization occurred as the liquid test substance coated the surface of the heated beads and air flowed up through the column. The test substance vapors were piped to a tee prior to the nose-only system where the concentration mixed with oxygen and humidified air. Oxygen was added from a compressed oxygen cylinder (5.0 research grade, Praxair Inc., Danbury, Connecticut, U.S.A.) using a regulator (model no. 3051301-01-MIB, Concoa, Virginia Beach, Virginia, U.S.A.) and an Omega rotameter-type flowmeter (model no. FL-3905G-HRV). Humidified air was added using a Coilhose Pneumatics Regulator (model no. 8802K). A rotameter-type flowmeter (model no. VFB-69-BV, Dwyer Instruments, Inc., Michigan City, Indiana, U.S.A.) was use to control the compressed air that passed through a muffler-type bubbler submerged in a 2-L Erlenmeyer flask filled with deionized water. The aerosol atmosphere was delivered to the nose-only exposure system through 3/4-inch Tygon ® 

### tubing. The exhaust atmosphere passed through the in-house exhaust system before being released from the facility. The parameters used for this study are summarized in the following table:

### D. Methods Of Characterization Of Exposure Atmospheres

1. Nominal Concentrations

The nominal exposure concentration was calculated for the exposure as the total amount of test substance used during the exposure divided by the total volume of air that passed through the chamber during the exposure, using the following equation:

Test Substance Used (g) × MV × 10 6 

### Nominal Concentration (ppm) = TAV × GMW

Where

MV = Molar volume at GMW = Gram molecular weight of the test substance,

TAV = Total air volume of exposure, L

10 6 

### = ppm conversion

2. Analyzed Concentrations

Analyzed exposure concentrations were determined at approximately 60-minute intervals using a gas chromatograph (GC). Samples of the exposure atmosphere were collected from the chamber using an internal gas-sampling valve and sample loop. The chromatograph was displayed and the area under the sample peak was calculated and stored. The concentration in parts per million (ppm) was calculated using a ln-quadratic formula based on the GC calibration curve. The following table summarizes the gas chromatograph conditions:

The GC was calibrated using gas-phase standards prepared to contain known vapor concentrations of the test substance prepared in 10-L Tedlar ® 

### gas bags (SKC, Inc., Eighty Four, Pennsylvania, U.S.A.). Standard bags were prepared by metering a known amount of air into the bag using a dry test meter (Model DTM-200A, Elster American Meter Co., Nebraska City, Nebraska, U.S.A.) and injecting a known volume of test substance. Using a hand-held heated blower, the bag was warmed until total volatilization of the test substance was visually observed. A sample was collected from the bag for approximately 8 minutes prior to being run through the GC. The concentrations of the gas-phase standards were calculated as follows:

VOL × R × T × D × 10 -3 

### × 10 6 

### Concentration (ppm) = L × GMW × P

Where:

VOL = Volume of test substance vaporized into bag, μL

R = Universal constant,

T = Nominal laboratory temperature in K (273 + 21°C = 294 K)

D = Density of the test substance,

L = Volume of air used to prepare bag,

GMW = Gram molecular weight,

P = Nominal laboratory barometric pressure,

### = Conversion factor to ppm

Prior to initiating animal exposure, the GC was calibrated with standards prepared and analyzed in triplicate. The calibration curve was defined using standards prepared at 4 vapor concentrations spanning an appropriate range relative to the target exposure concentrations for the study. The prime calibration curve was prepared for the target concentration using the quadratic formula. The integrated peak area (y) and the theoretical concentrations of the calibration standards (x) were fit with least-squares regression analysis to the ln-quadratic

formula:

ln (y) = a × [ln(x)] 2

E. Route And Rationale Of Test Substance Administration

The selected route of administration for this study was inhalation exposure since this is a reliable and accurate method of evaluating toxicity and is the possible route of human exposure. The nose-only exposure method was selected to reduce test substance requirements and minimize dermal absorption. The animal model, the albino rat, is generally recognized as appropriate for acute inhalation toxicity studies.

F. Animal Receipt And Acclimation

The Crl:CD(SD) rats used for this study were received in good health from Charles River Laboratories, Raleigh, North Carolina, U.S.A., on January 15, 2007. The rats were uniquely identified by ear tags displaying the animal number and were acclimated to the laboratory for a minimum of 7 days. During the acclimation period, the rats were observed twice daily for mortality and moribundity. The animals were subjected to restraint in the nose-only exposure holding tubes for 1 hour on January 22, 2008 prior to test substance exposure.

G. Animal Housing

Upon arrival, all animals were housed in individual suspended wire-mesh cages. The animals were maintained by the Animal Husbandry staff of in accordance with standard operating procedures (SOP). On the day of exposure, the animals were placed in nose-only exposure holding tubes in the animal room, transported to the exposure room, exposed for the requisite duration then returned to their home cages.

I. Environmental Conditions

The animal room was maintained with controlled temperature, humidity and light (12 hours light/12 hours dark). The room temperature and humidity controls were set to maintain daily averages of 71 ± 5°F (22 ± 3°C) and 50 ± 20% relative humidity. Room temperature and relative humidity were monitored using the Metasys DDC Electronic Environmental control system and were scheduled for data collection on an hourly basis. These data are summarized in Appendix B. Actual mean daily temperature ranged from 70.4°F to 70.6°F (21.3°C to 21.5°C) and mean daily relative humidity ranged from 35.9% to 48.1% during the study.

J. Assignment Of Animals To Treatment Groups

Animals used in the study were selected from available stock and assigned to groups using an arbitrary assignment. The animals were selected based on body weight requirements and on the appearance of general good health. The selected animals were approximately 8 weeks old at initiation of exposure; body weight values ranged from 276 g to 294 g for males and from 207 g to 226 g for females. Individual body weights at assignment were within ± 20% of the mean for

each sex.

### DEVIATIONS FROM THE PROTOCOL

This study was conducted in accordance with the protocol and protocol amendments, except for the following.

• Protocol Section 7.5 states that the daily average temperature of the exposure atmosphere will be 22 ± 2°C. On January 23, 2008, the average temperature of the exposure atmosphere was 25°C.

This deviation was a result of the amount of heat required to completely vaporize the test substance and did not negatively impact the quality or integrity of the data nor the outcome of the study. Acute Inhalation Toxicity Study of in Albino Rats
