Used primarily as an intermediate in peptide synthesis, this compound plays a key role in the protection of amino groups during the stepwise construction of complex peptides. The Boc (tert-butoxycarbonyl) group allows for reversible protection, enabling selective deprotection under mild acidic conditions without affecting other sensitive functional groups in the molecule. Its long aliphatic chain enhances lipophilicity, making it useful in the design of bioactive peptides with improved membrane permeability. It is also employed in the synthesis of modified amino acids for pharmaceutical research and in the development of peptidomimetic drugs targeting metabolic and neurological disorders.
