General description
1,2-Ethanedithiol (EDT) is an organosulfur compound that is used as an organic building block in chemical synthesis. It is also used as a ligand for metal ions to prepare metal complexes.
Application
1,2-Ethanedithiol can be used to synthesize:
- 1,3-Dithiolanes by reacting with aldehydes or ketones.
- Dithiazepan-3-yl-alkanoic acids by cyclocondensation reaction with amino acids and formaldehyde.
- EDT can also be used as a scavenger in solid phase peptide synthesis for the efficient deprotection of the peptide resin.
