Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of compounds with biological activity. It serves as a building block in organic synthesis, especially in reactions requiring amine functionality with electron-withdrawing nitro groups for further modification. Commonly employed in the development of dyes, fluorescent probes, and sensors due to its ability to participate in condensation and coupling reactions. Also utilized in research settings for labeling and derivatization of biomolecules.
