Application

1,2-Ethanedithiol can be used as a reactant to synthesize:
  • Aryl thiols via copper-catalyzed single-step reaction with aryl halides.
  • 1,3-Dithiolanes via Lewis acid-catalyzed chemoselective condensation with carbonyl compounds.
  • Polyalkylene sulfides via polycondensation with dibromides in the presence of NaH.

Protocols

Fmoc resin cleavage and deprotection follows the difficult task of detaching the peptide from the resin support and removing all the side-chain protecting groups of the amino acid residues to yield the desired peptide.

Overcome challenges in synthesis and disulfide bond formation with protocols for Fmoc solid-phase peptide synthesis of peptides with cysteine and methionine.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
