**HAZARDOUS SUBSTANCES DATABANK**

Note: The fields WLN and OHMN have been removed from HSDB.

Section 0 - Administrative Information

HSN - HAZARDOUS SUBSTANCES DATABANK NUMBER

The Hazardous Substances Databank Number is a unique identification
number, up to 4 digits, assigned by NLM for internal control.

DATE - LAST REVISION DATE

The DATE field shows the last revision date or the date of the last
revision or modification to the record. The format is YYYYMMDD.

RVDT - LAST REVIEW DATE

The Last Review Date indicates the most recent date on which the HSDB
record was peer reviewed by the Scientific Review Panel (SRP).

UPDT - UPDATE HISTORY

This Field records the update history, in reverse chronological order,
of the record. It will show the dates the record was updated and the
type of update performed.

NO - NOTES

This field provides an explanation of how the data have been distributed
among various related chemical records. For example, the NO field will
describe how information has been distributed among a metal cluster,
including the elemental metal record, the generic metal compounds
record, and the individual compound-specific records. If there is
information in the NOTES field, then it will automatically display,
together with NAME and RN, with any PRINT command. The field cannot be
searched.

Section 1 - Substance Identification

NAME - NAME OF SUBSTANCE

Usually a single, common, generally recognized name of the chemical
substance.

RN - CAS REGISTRY NUMBER

A number of up to nine digits assigned by Chemical Abstracts Service
(CAS) to uniquely identify a chemical substance. The number is searched
and displayed without leading zeroes in a hypenated format. For example,
Formaldehyde has the CAS Registry Number: 50-00-0

The last digit of the Registry Number serves as a check digit in a
formula to verify that the number is a valid RN. Searching for a
Registry Number qualified by (RN) will give the following special error
message if the RN is invalid and, thus, the check digit is erroneous:

> EXAMPLE:
>
> USER:
>
> (RN) 50-00-9
>
> NP (INVALID CHECK DIGIT ON 50-00-9 PLEASE VERIFY YOUR CAS REGISTRY
> NUMBER)
>
> \*NONE-

Note that if the Registry Number is otherwise incorrect, e.g., not
properly hyphenated or too many digits in the check position, you will
receive the standard NP message. The standard NP message also displays
if the Registry Number you are searching is valid but not present in the
database being searched.

RELT - RELATED HSDB RECORDS

This field lists other HSDB records for chemical substances which are
chemically similar to the title chemical and may, therefore, have
additional information of interest to the user. The data includes the
HSDB record number (HSN) and the corresponding NAME for each related
record. In many cases the reason for the relatedness will also be
indicated. The keywords used to describe the relatedness are described
below:

ANALOG - A structural derivative that may differ from the title chemical
by only a single element or substituent group, such as hydrates, salts,
anhydrides or free acids.

CONTAMINANT - An impurity commonly found in the title chemical that may
significantly contribute to its toxicity or environmental fate.

DEGRADATION PRODUCT - A decomposition product, resulting from the
chemical degradation of the title chemical, that persists long enough to
contribute to its toxicity or environmental fate.

ISOMER - A substance with the same molecular formula as the title
chemical but with a different molecular arrangement.

METABOLIC PRECURSOR - A chemical substance, such as the initial or
intermediate compound in a chain of enzymatic reactions, that gives rise
to the title chemical and may contribute to its toxicity.

METABOLITE - A chemical substance, produced by the enzymatic breakdown
of the title chemical, that contributes significantly to its toxicity or
can be diagnostic of exposure to the title chemical.

MIXTURE - A mixture which contains the title chemical.

MIXTURE COMPONENT - Any of the consitutents that make up the mixture
(i.e., the title compound). Isomeric components are included in this
category when the structure of the title chemical is unspecified.

SY - SYNONYMS

Additional chemical, generic, trivial or trade name(s) of the chemical
substance (if single entity compound).

MF - MOLECULAR FORMULA

The elemental composition of a chemical substance in terms of the number
and kinds of atoms contained in its structure. The formula is ordered
according to the \"Hill Convention\", which is Carbon first, followed by
Hydrogen and then in alphabetic sequence by the remaining atomic
symbols. For example: C21-H32-N2-O5-S. The designation UVCB indicates
that the molecular formula is of Unknown or Variable composition,
Complex reaction products, or Biologicals.

RTEC - RTECS NUMBER

A 9-position accession code (2 letters followed by 7 numbers, e.g.,
AAnnnnnnn) assigned by NIOSH to each primary chemical name in Registry
of Toxic Effects of Chemical Substances (RTECS).

SHPN - SHIPPING NAME/NUMBER - DOT/UN/NA/IMO

The DOT (Department of Transportation) number, identical to the UN
number, identifies the proper shipping name of hazardous wastes under 49
CFR 170. The NA number is for chemicals not recognized for international
shipment except to and from Canada. The IMO numerical designation is
from the International Maritime Dangerous Goods Code of the
International Maritime Organization in London. Examples: UN 1554, NA
2902, and IMO 3.1

STCC - STCC NUMBER

The Standard Transportation Commodity Code is a 7 place numeric code;
the first 2 digits are usually 49 followed by a 5 digit code. Example:
49 066 35

HAZN - EPA HAZARDOUS WASTE NUMBER

A four character alphanumeric number, consisting of one alphabetic
followed by three numerics, assigned by the Environmental Protection
Agency (EPA) as provided under 40 CFR, Subparts C and D. For each
hazardous substance the code specifies compound name, waste source,
and/or hazardous characteristic (ignitability, corrosivity, reactivity,
or toxicity). Example: F003

ASCH - ASSOCIATED CHEMICALS

Indicates chemical substances for which there are no HSDB records but
information about these can be found in the HSDB record for the title
compound. For example, there are no HSDB records for sodium saccharin or
calcium saccharin, but the HSDB record for saccharin (HSN #669) does
contain information about these salts, and so their names and CAS
Registry numbers will be found in the ASCH field. The format for this
field is chemical name; CAS Registry Number, e.g., Sodium Saccharin;
128-44-9. This field can be searched by the chemical name or by the CAS
Registry Number.

The Registry Number is a number of up to nine digits assigned by
Chemical Abstracts Service (CAS) to uniquely identify a chemical
substance. The number is searched and displayed without leading zeroes
in a hypenated format. For example, Formaldehyde has the CAS Registry
Number: 50-00-0

The last digit of the Registry Number serves as a check digit in a
formula to verify that the number is a valid RN. Searching for a
Registry Number qualified by (ASCH) will give the following special
error message if the RN is invalid and, thus, the check digit is
erroneous:

> EXAMPLE:
>
> USER:
>
> (ASCH) 50-00-9
>
> NP (INVALID CHECK DIGIT ON 50-00-9 PLEASE VERIFY YOUR CAS REGISTRY
> NUMBER)
>
> \*NONE-

Note that if the Registry Number is otherwise incorrect, e.g., not
properly hyphenated or too many digits in the check position, you will
receive the standard NP message. The standard NP message also displays
if the Registry Number you are searching is valid but not present in the
database being searched.
