1,2-Ethanedithiol Chemical Properties,Uses,Production
Chemical Properties
1,2-Ethanedithiol has a repulsive odor.
Occurrence
Reported found in beef (boiled, cooked) and chicken (cooked)
Uses
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.
Preparation
Prepared by reacting ethanol, thiourea and ethylene dibromide and subsequent alkaline hydrolysis of the ethylenediisothiuronium bromide
General Description
1,2-Ethanedithiol (1,2-Dimercaptoethane, Dithioglycol, Ethylene mercaptan) is an organo sulfur compound. It affords monomeric, dimeric and polymeric complexes on reaction with Pt(PPh3)4, Pd(PPh3)4 and Ni(PPh3)4. It has been synthesized by refluxing 1,2-dichloroethane with thiourea in ethanol.
Hazard
Vapors cause severe headache and nausea.
Safety Profile
Poison by ingestion, intraperitoneal, and intravenous routes. When heated to decomposition it emits very toxic fumes of SOx. See also MERCAPTANS .
