Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its structure allows for functionalization in drug design, especially in compounds targeting enzyme inhibition. Commonly employed in the preparation of sulfonamide-based bioactive molecules due to the electron-withdrawing nature of the sulfonyl group and the hydrogen-bonding capability of the aniline moiety. Also utilized in the synthesis of dyes and functional materials where aromatic amines contribute to chromophore formation.
