H-D-Ala-OtBu.HCl（Cat No.:R061157）is a protected derivative of the amino acid D-alanine (D-Ala), where the carboxyl group is esterified with a t-butyl (OtBu) group for protection. The hydrochloride (HCl) salt form enhances solubility, allowing for easier use in aqueous-based peptide synthesis. The t-butyl ester prevents unwanted reactions at the carboxyl group during solid-phase peptide synthesis (SPPS), enabling the selective incorporation of D-alanine into peptides. This compound is widely used in peptide chemistry and drug development, particularly in studies of peptide structure, function, and interactions in various biological processes.
