General Description
Colorless low-melting solid or liquid with a slight ethereal odor. Mp: 26.5°C; bp: 92.5°C. Density (of liquid): 1.64 g cm-3 at 30°C. Used as a refrigerant, a solvent extractant, and in dry cleaning.
Reactivity Profile
1,1,2,2-tetrachloro-1,2-Difluoroethane is non-flammable. Incompatible with active metals such as potassium, sodium, beryllium, powdered aluminum, zinc, magnesium, and calcium. Reacts with acids.
Potential Exposure
Possible risk of forming tumors, Primary irritant (w/o allergic reaction).
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. (This is particularly true of the 1,1,1,2-compound).
Shipping

Incompatibilities
Acids and chemically active metals, such as potassium, beryllium, powdered aluminum; zinc, calcium, magnesium, and sodium.
Chemical Properties
Colorless liquids or solids with slight ethereal odor.
Chemical Properties
White solid or colorless liquid; slightly
camphor-like odor when concentrated. Insoluble in
water; soluble in alcohol. Nonflammable.
Physical properties
Clear, colorless liquid or solid with a faint, ethereal or camphor-like odor. Evaporates quickly
when spilled.
Hazard
Toxic by inhalation.
Health Hazard
At high concentrations, 1,1,2,2-
tetrachloro-1,2-difluoroethane affects the nervous
system and causes pulmonary edema in
animals; it is expected that severe exposure in
humans will produce the same effects.
There are no reports of adverse effects in
humans.
