Used primarily as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes, which are widely applied in textiles, leather, and paper industries. It also serves as a precursor in the production of certain pharmaceuticals and agrochemicals. In research, it is utilized for studying nitroaromatic compounds and their reactivity. Additionally, it finds application in organic synthesis for creating complex molecules. Proper handling is essential due to its toxic and potentially hazardous nature.
