Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a protected form of 4-bromophenylamine, allowing selective reactions at other sites in the molecule without interference from the amine group. The tert-butyloxycarbonyl (Boc) protecting group can be removed under mild acidic conditions, making it valuable in multi-step synthesis. Commonly applied in the development of active pharmaceutical ingredients (APIs) where controlled amine reactivity is required. Also utilized in the synthesis of functionalized anilines for use in medicinal chemistry and in the creation of specialty polymers.
