H-Asp(OtBu)-OtBu.HCl（Cat No.:M119609）is a protected form of aspartic acid (Asp), where both the carboxyl and hydroxyl groups are esterified with t-butyl (OtBu) groups, providing protection during peptide synthesis. The t-butyl ester groups prevent undesired reactions at the carboxyl and hydroxyl positions, allowing for selective peptide bond formation. The hydrochloride (HCl) salt form enhances solubility in aqueous solutions, facilitating its use in biochemical applications. This compound is primarily used in solid-phase peptide synthesis (SPPS) to incorporate aspartic acid into peptides, making it a valuable tool in peptide chemistry and drug development.
