CAS Number: 75-45-6. A colorless gas with a faint, sweetish odor.
Used as a propellant, refrigerant and solvent. Chemical formula =
CHClF2. Molecular weight = 86.48 g/mol.

CAS Number: 108-94-1. A watery white to pale yellow liquid with a
peppermint or acetone-like odor. Used widely as a solvent and in
the preduction of other organic chemicals. Chemical formula =
C6H10O. Molecular weight = 98.14 g/mol.

CAS Number: 123-86-4. A clear, colorless liquid with a mild,
fruity odor. It is used as an industrial solvent, in the
manufacture of lacquer, and in artificial perfumes and flavoring
agents. Chemical formula = C6H12O2. Molecular weight = 116.16 g/mol.

Also known as: 2-butanone peroxide. CAS Number: 12338-12-4. A
flammable, clear liquid that is used as a curing agent for
polyester resins. Chemical formula = C4H16O4. Molecular weight =
176.21 g/mol.

CAS Number: 74-90-8. A naturally occurring substance found in a
number of foods and plants. It found in the air as a result of
the combustion of gasoline in automobile engines. It is also
emitted during chemical processing and other industries, as well
as from incineration of municipal waste. It is also released in
cigarette smoke. Chemical formula = CN. Molecular weight = 27.02
g/mol.

CAS Number: 16065-83-1. A steel-gray solid with a high melting
point. It is used in the production of steel and other metal
alloys. It is a naturally occurring element in rocks, soils,
animals and plants. Chemical formula = Cr. Molecular weight =
51.996 g/mol.

CAS Number: 1327-53-3. A white or transparent solid in the form
of glassy, shapeless lumps, or a crystalline powder that
resembles sugar. It has no odor or taste. It is produced from
by-products of copper smeltin. It is then used in the
manufactore of other arsenic compounds which are used as wood
preservatives, insecticides and herbicides. It is also used in
metallurgical process and in the manufacture of glass and
ceramics. Chemical formula = As2O3. Molecular weight = 197.84
g/mol.

CAS Number: 91-57-6. A solid substance that is used to make other
chemicals, such as dyes and resins. It is also used to make
vitamin K. It is also present in cigarette smoke, wood smoke,
tar, and asphalt. Chemical formula = C11H10. Molecular weight =
142.2 g/mol.

Also known as: Ethylene glycol monoethyl ether acetate. CAS
Number: 111-15-9. A clear liquid with an ether-like odor. It is
used as a solvent, in automobile lacquers to prevent evaporation
and create a high gloss, and in printing inks, photographic
films, lacquers and nail polish. Chemical formula = C6H12O3.
Molecular weight = 132.16 g/mol.

Also known as 1,2-Dichloroethene (Total). CAS Number: 540-59-0.
It is a highly flammable, colorless liquid with a sharp,
ether-like odor. There are two forms of 1,2-dichloroethene; one
form is called cis-1,2-dichloroethene and the other is called
trans-1,2-dichloroethene. This is the combination of those forms
in a mixture.

1,2-Dichloroethene is used most often to produce solvents and in
chemical mixtures.
