Used in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected intermediate, where the BOC group safeguards the amino group during the coupling process. This allows for the sequential addition of amino acids to form longer peptide chains. Commonly applied in the production of peptides for pharmaceutical research, drug development, and biochemical studies. Its stability and ease of deprotection make it a reliable choice for creating specific peptide sequences with high precision.
