Primarily used as an intermediate in the production of dyes, pigments, and other organic compounds. It serves as a precursor in the synthesis of p-toluidine, which is further utilized in manufacturing colorants for textiles, paper, and leather. Additionally, it is employed in the synthesis of agricultural chemicals, such as pesticides and herbicides. In the pharmaceutical industry, it acts as a building block for certain drugs and active pharmaceutical ingredients. Its role in chemical research includes being a standard or reference compound in analytical studies and quality control processes, such as verification and quantification of p-Nitrotoluene in samples using techniques like Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC).
