Used primarily as a derivatizing agent in organic synthesis, especially in the preparation of protected intermediates for pharmaceuticals and agrochemicals. It reacts selectively with primary and secondary amines to form carbamates, which helps in blocking amine functionality during multi-step syntheses. Commonly employed in the production of active pharmaceutical ingredients (APIs) where controlled reactivity and stability of intermediates are required. Also utilized in the synthesis of peptides and heterocyclic compounds due to its ability to modify functional groups under mild conditions. Its bromophenyl group allows for further functionalization via cross-coupling reactions, making it valuable in building complex molecular architectures.
