Used primarily as an intermediate in the production of dyes, pigments, and other organic compounds. It plays a key role in synthesizing chemicals like 4-nitrotoluene-2-sulfonic acid, which is further used in manufacturing brightening agents and colorants. Additionally, it serves as a precursor in the synthesis of pharmaceuticals and agrochemicals. In industrial settings, it is also employed in the preparation of explosives and as a solvent in certain chemical reactions. Proper handling and safety measures are essential due to its toxic and potentially hazardous nature.
