Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a protected aniline derivative, where the tert-butoxycarbonyl (Boc) group stabilizes the amine during reactions, allowing selective functionalization at other sites. The bromine substituent enables further transformations via cross-coupling reactions such as Suzuki or Heck couplings, making it valuable in constructing complex aromatic systems for drug discovery. Commonly employed in the development of bioactive molecules where controlled amine reactivity is required.
