This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for the creation of complex peptides and proteins, particularly in pharmaceutical research and development. The Boc (tert-butoxycarbonyl) group protects the amino functionality during the synthesis process, preventing unwanted reactions and ensuring the correct sequence of amino acids. Its tert-butylphenyl side chain can influence the peptide's hydrophobicity and binding properties, making it valuable in designing molecules with specific biological activities. It is often employed in the development of drug candidates, especially in targeting enzymes, receptors, or other proteins involved in disease pathways, including those related to the nervous system and metabolic disorders. Additionally, it can be used in the study of structure-activity relationships (SAR) to optimize the efficacy and selectivity of therapeutic peptides.
