DL-Homocysteine thiolactone Hydrochloride

DL-Homocysteine thiolactone Hydrochloride (CAS 6038-19-3) is the hydrochloride salt form of DL-homocysteine thiolactone — a cyclic thioester derivative of the naturally occurring amino acid homocysteine. The thiolactone ring makes this compound highly reactive toward nucleophiles, particularly lysine residues in proteins, enabling unique conjugation and modification chemistry.
With the molecular formula C₄H₈ClNO₂S and a molecular weight of 169.63 g/mol, it exists as a white to off-white crystalline powder that is freely soluble in water and polar solvents. It is hygroscopic and should be stored in a sealed container at 2–8 °C under dry conditions.
