Ortep (Oak Ridge Thermal Ellipsoid Plot program) generates ball-and-stick 
type crystal structure illustrations.  

It uses crystallographically determined atomic positions and thermal 
parameters and produces thermal-motion probability ellipsoids on the atomic 
sites.

Clenbuterol is 

2-(4-Amino-3,5-dichlorophenyl)-2-hydroxy-1-(t-butylamino)ethane

and is used as an anti-asthmatic. It is related to salbuterol, which is 
one of the most popular anti-asthmatics in Europe, although the FDA dont 
like it too much, so theophylline is preferred in the US. One of the 
british athletes sent home from Barcelona was found to have been taking 
it, and such is the density of the press (>13.6) that thay were 
clamouring about steroid this and steroid that. Pathetic, really.

That sounds right.  Incidentally, the rxn is highly exothermic (only logical,
considering that it produces tens of liters of gas in milliseconds), meaning
that a people suffer second or third degree burns from airbags.  Auto
manufacturers (and most folks tend to agree) that this is a reasonable
price for an increased survival rate.

If you want more info, why not write to the automakers?  I worked for GM for
a summer, and they were only too eager too tell everybody about their airbags,
since theirs are supposedly the coolest (they are only about 180 degrees C).

Calcium propionate is the calcium salt of propionic acid (aka
propanoic acid), thus:

Dear Sir,
As for myself, (I do not propose to speak for anyone else), I DID get 
my information from a Handbook of Chemical Hazards in the lab (also
referenced in said post, if you want it again I will have to go
find it again...next week, I am at a conference this week) and
Methylene Chloride IS a potentially hazardous chemical.  Yes, I am
sure it is used for the purposes as stated in the Merck, but in what ways
and what concentrations.  The original Post asking for information
the couple was worried about a potentially significant amount of material
(one industrial drum visible (?)) and the wife is pregnant.  That is
the real concern they had, potential effects upon an unborn child.
Now, I would agree that a useful discussion of safety of materials
Should include references and consideration of what is a significant concentration
for concern.  I agree that one could waste their entire life sitting at
home worrying about the effect of this and the effect of that, but
I do not find a "so what" attitude a rational replacement either.
Personally I would prefer, particularly where someone's health might be 
concerned, to be a "little" over cautious than a little careless.  That
is why I stated the potential side effects for exposure and suggested that
IF they had noticed any of those they might then care to follow up.
Where then do you draw the line for your balance?( for there must be
an acceptable balance between the concerns over safety and the desire
to be done with an issue.....Which leads me to ask, is the fellow
who made the original post still around?  Irregardless I am sure this thread
has gone about as far previously as it needed to, but I would like
to know what they did in follow up if anything........

Hi everyone..

   I suppose this is a chemistry-related question..

   I recently bought some frozen pizza -- MaMa ROSA's Party Pizza, or something,
and right under the name on the packaging it says in bold letters "Calcium
propionate added to retard spoilage of crust."  It's almost as if that's part
of the name of the pizza, the way they put it.
   Needless to say, I was just curious to know what this calcium propionate
stuff is..  (I don't remember it from first year chemistry at college.)  Why
do they note its presence so liberally on the packaging?

Curiously,

Without going into the chemistry of Clenbuterol: this compound is a very
potent performance enhancer used in athletics and the body-building community instead of steroids. Though it has been proven to increase lean-muscle massby up to 33 % during a six-week cycle it also shows serious side-effects.Side effects can include but are not limited to cardiac rhtyhm irregularties, "clenbuterol tremor" (uncontrolable tremor of the extremeties), and so on. All these side effects are due to stimulation of vegetative system.In short, Clenbuterol is definitly not a harmless vitamin-supplem


ent, but it makes your body grow.

I can't answer the above questions, but I can say as a fellow chemist that
I understand the so-called irrational fear of the populace.  They've been
lied to, spit upon, etc., in the past.  Companies use obscure names in 
listing ingredients of their products, etc.  Then they are told "better
living through chemistry".  Even if this particular company is saintly,
because of all the other mistreatments the public will disbelieve them
when they say this.  It is not the chemist's fault---it is government
and greedy commerce that have done this.  Anyway, are all chemists
safety conscious?  Just a little input.

A quick trip to the chem library where I work uncovered the following
data for the solubility of methylene chloride in water.

Methyene chloride will dissolve in water to give a 1.30 weight % solution

Water dissolves in methylene chloride to give a 0.198 weight % solution

The CH2Cl2 is in so low concentrations that it will be soluble in water.
The solubility should be in the ppm range, maybe as low as ppb. It will 
acumulate in fat, fish, birds, etc. In air it is broken down by reaction
with atmospheric OH radical. It does not destroy ozone.

The CRC Handbook, in their section on the elements describes an allotrope of
carbon as "white" carbon, in addition to diamond and graphite allotropes. They
devote a couple sentences to it and state that not much is known about it.
Does this have anything to do with 'buckyballs'? They do not mention them, even
in the latest edition.  Does anyone know anything about 'white' carbon beyond
what's listed in the CRC?

Also an old (1950s) encyclopedia lists, in addition to O2 and ozone O3, a form
of oxygen as O4, an unstable bluish nonmagnetic substance that readily
decomposed to O2.  I have never seen any other reference to this.  Does O4
