Used as a key intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where protection of the amine group is required. The Boc-protected amine allows selective functionalization of the phenolic hydroxyl group during multi-step syntheses. Commonly employed in the preparation of drug candidates involving aromatic amine scaffolds, including those targeting central nervous system disorders and anti-inflammatory agents. Its stability under various reaction conditions makes it suitable for use in peptide chemistry and combinatorial library synthesis.
