This chemical is primarily used in peptide synthesis as a protected form of tryptophan. The Boc (tert-butoxycarbonyl) group safeguards the amino group during the synthesis process, preventing unwanted reactions. It is particularly valuable in solid-phase peptide synthesis (SPPS), where sequential addition of amino acids is required. The Boc protection allows for selective deprotection and coupling steps, ensuring the correct sequence of the peptide chain. After the synthesis is complete, the Boc group can be removed under acidic conditions, revealing the free amino group. This compound is essential in producing peptides for research, pharmaceuticals, and biotechnology applications, including the development of therapeutic peptides and biochemical studies.
