Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where nitroaniline derivatives serve as building blocks for nitrogen-containing heterocycles. Its functional groups enable selective transformations, making it valuable in the preparation of dyes, agrochemicals, and specialty organic compounds. The bromo and nitro groups allow for cross-coupling reactions and subsequent reductions, facilitating the construction of complex molecules in research and industrial settings.
