Used primarily in organic synthesis as a building block for peptides and other complex molecules. It features a BOC (tert-butoxycarbonyl)-protected N-methylamino group, which protects the amine during chemical reactions, ensuring selective modification of other functional groups such as the carboxylic acid. Commonly employed in the development of pharmaceuticals, particularly in the synthesis of drug intermediates. The BOC group is easily removable under mild acidic conditions, making it versatile in multi-step synthesis processes. Additionally, it is utilized in research for creating modified amino acids and studying their biological activities.
