Used primarily as a protected amino acid derivative in peptide synthesis. The Boc (tert-butoxycarbonyl) group acts as a protecting group for the amino functionality, preventing unwanted reactions during coupling steps. This compound is especially useful in solid-phase and solution-phase peptide synthesis where selective deprotection under mild acidic conditions is required. It allows for the stepwise construction of complex peptides without affecting other functional groups. Commonly employed in pharmaceutical research and development for synthesizing bioactive peptides and peptidomimetics.
