H-D-Aha-OH hydrochloride (Cat No.: I042587) is the hydrochloride salt of D-2-aminohexanoic acid (D-Aha), a synthetic, non-proteinogenic amino acid analog of lysine. Featuring a six-carbon aliphatic side chain terminating in an amino group, D-Aha serves as a flexible spacer or lysine mimic in peptide synthesis. The D-configuration enhances resistance to proteolytic degradation, making it valuable in designing stable peptide-based drugs or probes. The hydrochloride form improves solubility and handling, supporting its use in medicinal chemistry, peptide engineering, and structure–activity relationship studies.
