Used as an intermediate in the synthesis of azo dyes and pigments, particularly for producing yellow and orange shades with good lightfastness. Employed in the preparation of heterocyclic compounds for pharmaceutical applications, including antimicrobial and anti-inflammatory agents. Also utilized in the development of sensors and reagents for analytical chemistry due to its ability to form colored complexes with certain metal ions. Its nitro and hydrazine functional groups make it valuable in coupling reactions and the production of specialty chemicals.
