This compound is primarily utilized in peptide synthesis as a protecting group for the hydroxyl and amino functionalities of serine. The Boc (tert-butoxycarbonyl) group safeguards the amino group, while the tert-butyl moiety protects the hydroxyl group, ensuring selective reactions during peptide chain assembly. The dicyclohexylamine salt form enhances the compound's stability and solubility, making it easier to handle in organic synthesis. It is particularly valuable in solid-phase peptide synthesis (SPPS) and other applications where precise control over amino acid reactivity is required. Its use enables the construction of complex peptides with high purity and efficiency.
