Used primarily in organic synthesis as a protected boronic ester intermediate for Suzuki-Miyaura cross-coupling reactions. The tert-butyl carbamate (Boc) group stabilizes the aniline moiety during coupling, allowing selective formation of biaryl structures commonly found in pharmaceuticals and agrochemicals. After coupling, the Boc group can be easily removed under mild acidic conditions to release the free amine for further functionalization. This compound is especially valuable in the synthesis of complex aromatic amines and drug candidates where chemoselectivity and functional group tolerance are critical.
