This chemical is primarily used in peptide synthesis as a protecting group for amino acids. The BOC (tert-butyloxycarbonyl) group safeguards the amino group, while the ALOC (allyloxycarbonyl) protects the side chain of lysine. This dual protection allows for selective deprotection during the synthesis of complex peptides, ensuring precise control over the sequence and structure. It is particularly valuable in solid-phase peptide synthesis (SPPS), where stepwise assembly of peptides is required. The DCHA (dicyclohexylamine) salt form enhances stability and solubility, making it easier to handle and store. This compound is essential in the production of pharmaceuticals, bioactive peptides, and research applications requiring high-purity peptides.
