(S)-6-(((Allyloxy)carbonyl)amino)-2-aminohexanoic acid hydrochloride is primarily used in the field of peptide synthesis. It serves as a protected amino acid derivative, where the allyloxycarbonyl (Alloc) group acts as a protecting group for the amino functionality. This allows for selective deprotection during the synthesis of complex peptides, ensuring that specific amino acids are incorporated at desired positions without unwanted side reactions. The compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in constructing peptides with high precision and purity. Additionally, its hydrochloride form enhances solubility in aqueous solutions, facilitating its use in various biochemical and pharmaceutical research applications. The compound’s role in peptide synthesis contributes to the development of therapeutic peptides, enzyme inhibitors, and other biologically active molecules.
