(tert-Butoxycarbonyl)-L-arginine hydrochloride（Cat No.:R061630）, abbreviated as Boc-L-Arg·HCl, is a protected form of the amino acid L-arginine, where the amino group is protected by a tert-butoxycarbonyl (Boc) group. This protection prevents side reactions during peptide synthesis, allowing the controlled incorporation of L-arginine into peptide chains. The hydrochloride salt form enhances the compound’s solubility in aqueous solutions, making it suitable for various biological and chemical applications. Once peptide synthesis is complete, the Boc group can be removed under mild acidic conditions, revealing the free amino group for further reactions or modifications.
