Used primarily in peptide synthesis, this compound serves as a protected form of D-aspartic acid. The Boc (tert-butoxycarbonyl) group safeguards the amino functionality, while the OcHex (cyclohexyl ester) group protects the side chain carboxyl group during the synthesis process. This protection is crucial to prevent unwanted side reactions and ensure the correct sequence of amino acids in the final peptide product. It is particularly valuable in the production of complex peptides and proteins, where precise control over the assembly of amino acids is essential. Additionally, its application extends to the development of pharmaceuticals, where modified peptides are often used as active ingredients or intermediates in drug synthesis.
