What is 2-Chloroethyl ethyl sulfide?

Chemical properties

clear colourless to light yellow liquid

The Uses of 2-Chloroethyl ethyl sulfide

2-Chloroethyl Ethyl Sulfide is used as a reagent in the synthesis of furfuryl xanthines as adenosine receptor antagonists. It is also used as a reagent in the synthesis of methoxypropyl xanthines as putative A2B receptor antagonists.

General Description

2-Chloroethyl ethyl sulfide is a monofunctional analog of sulfur mustard (SM; 2,2′-dichloro diethyl sulfide). The mass diffusivity of 2-chloroethyl ethyl sulfide, a chemical warfare agent simulant, was studied.

Safety Profile

Poison by ingestion and subcutaneous routes. Mutation data reported. A severe skin and eye irritant. See also ETHERS and SULFIDES. When heated to decomposition it emits very toxic fumes of Cland SOx.
