L-LYSINE:2HCL UNLABELED is the hydrochloride salt form of L-lysine, a proteinogenic basic amino acid featuring a five-carbon aliphatic side chain terminating in a primary amine. The molecule contains both an amino group and a carboxyl group on the α-carbon framework, and the side-chain ε-amine is protonated under acidic salt conditions, with the "2HCl" indicating two equivalents of hydrochloride associated with the basic nitrogens. As an unlabelled, free amino acid salt, it is commonly used as a defined lysine source for peptide synthesis feedstocks, buffer or derivatization starting material preparation, and analytical workflows that require a chemically characterized lysine substrate.
CAT No: L-Iso-0412
