This chemical is widely used in peptide synthesis as a protecting group for serine residues. The BOC (tert-butyloxycarbonyl) group protects the amine functionality, while the AC (acetyl) group safeguards the hydroxyl side chain of serine, preventing unwanted reactions during peptide bond formation. The DCHA (dicyclohexylamine) salt form enhances the compound's stability and solubility, making it easier to handle in organic solvents. It is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase synthesis, where selective deprotection of the BOC group can be achieved under mild acidic conditions, allowing for precise control over the peptide assembly process. Its application ensures high purity and yield in the production of complex peptides for pharmaceutical and biochemical research.
