It is used as a pharmaceutical intermediate. Photocatalytic oxidation of gaseous 2-chloroethyl ethyl sulfide over TiO2 illuminated with UV light and maintained at 25 or 80°C in air was found to suffer progressive oxidation to yield ethylene, chloroethylene , ethanol, acetaldehyde, chloroacetaldehyde, diethyl disulfide, 2-chloroethyl ethyl disulfide and bis(2-chloroethyl) disulfide as the main primary intermediates, and water (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), surface sulfate ions (SO42-), and hydrogen chloride (HCl) as the final products.

Miscible with water.

Store at room temperature. Incompatible with oxidizing agents.
