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.

Reaction conditions were defined for the selective quantitative derivatization and fluorophore labeling of phosphoserine residues on peptides and proteins. Phosphoserine was derivatized with 1,2-ethanedithiol using a modification of the reaction conditions defined by R. C. Clark and J. Dijkstra (1967)

Staphylococci are a major cause of infections associated with indwelling medical devices. Biofilm formation on these devices adds to the antibiotic resistance seen among clinical isolates. RNAIII-inhibiting peptide (RIP) is a heptapeptide that inhibits staphylococcal pathogenesis, including biofilm formation, by
