Descrizione generale

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.

Applicazioni

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.

Vibrational spectra of vapor-phase 1,2-ethanedithiol and 2-mercaptoethanol were recorded to investigate weak intramolecular interactions. The spectra were recorded with conventional absorption spectroscopy and laser photoacoustic spectroscopy in the 2000-11,000 cm(-1) region. The room temperature spectra of each molecule are complicated
