Applications
1,2-Ethanedithiol is used as a reagent in organic synthesis to convert carbonyl compounds to thioacetals (1,3-dithiolanes). It replaces the toxic reagent arsenic tirchloride, which is involved in the synthesis of membrane-permeant fluorogenic biarsenicals from precursor dyes fluorescein and resorufin. It acts bidendate ligand to form complexes with metal ions.

Solubility
Miscible with ethanol, acetone, ether and benzene. Slightly miscible with water.

Notes
Air sensitive. Keep away from sources of ignition. Incompatible with alkali metals. Avoid inhalation of its vapor.
