H-Ala-OtBu.HCl （Cat No.:R061159）is a compound consisting of the amino acid alanine (Ala) protected at the carboxyl group with a t-butyl ester (OtBu) group, along with a hydrochloride (HCl) salt form that enhances its solubility. This structure allows for the selective incorporation of alanine in peptide synthesis while preventing undesired reactions at the carboxyl site. The t-butyl ester is commonly used as a protective group in solid-phase peptide synthesis (SPPS). H-Ala-OtBu.HCl is used in peptide chemistry to synthesize peptides or in drug development, especially for studies involving alanine-rich sequences.
