Used in organic synthesis as a protected intermediate in the preparation of biologically active compounds, particularly in pharmaceutical development. The Boc-protected amine group allows for selective deprotection under mild acidic conditions, making it valuable in multi-step peptide and heterocyclic syntheses. Commonly employed in the construction of drug molecules where controlled functional group reactivity is required. Its carboxylic acid functionality enables coupling reactions with amines or alcohols to form amides or esters, facilitating the assembly of complex molecular architectures.
