S-tert-Butyl-L-cysteine hydrochloride（Cat No.:R061389）is a derivative of the amino acid L-cysteine, where the sulfur atom is protected by a tert-butyl group. This modification enhances the compound’s stability and solubility, making it useful in peptide synthesis and other biochemical applications. The tert-butyl group prevents unwanted reactions involving the thiol group during synthesis, allowing for selective incorporation of L-cysteine into peptides. After synthesis, the tert-butyl group can be removed under mild conditions, revealing the free thiol group, which is crucial for disulfide bond formation and other biochemical interactions. It is used in research and drug development.
