Ethyl chlorothioformate

Chemical properties

clear yellow or grey-greenish to purple liquid

Chemical properties

Ethyl chlorothioformate is a flammable clear yellow or amber-colored liquid. Pungent, penetrating odor.

General Description

An amber-colored liquid with a pungent penetrating odor. Flash point 125°F. Very toxic by inhalation. Corrosive to metals and tissue. Denser than water. Vapors heavier than air.

Air & Water Reactions

Flammable. Insoluble in water. On contact with moisture Ethyl chlorothioformate produces highly corrosive and toxic fumes of hydrogen chloride gas.

Reactivity Profile

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as sulfur oxides, hydrogen chloride, and carbon monoxide, may be formed when involved in fire.

Health Hazard

Exposure can cause irritation of eyes, nose and throat.

Potential Exposure

Used for making other chemicals. A pharmaceutical intermediate

Shipping

UN2826 Ethyl chlorothioformate, Hazard Class: 8; Labels: 8-Corrosive material, 6.1-Poison Inhalation Hazard, 3-Flammable liquid; Inhalation Hazard Zone B

Incompatibilities

Corrosive to metals. Flammable vapors may form explosive mixture with air. Contact with moisture releases highly corrosive and toxic hydrogen chloride gas. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices)
