  • Applications

    4-Nitrobiphenyl (CAS 92-93-3) is primarily used as an organic synthesis intermediate. It serves as a precursor to arylamine compounds (for example, after reduction to 4-aminobiphenyl) that feed the dye and pigment industry and related applications. It is also employed as a building block in colorant formulations for coatings and inks and is of interest as a precursor in materials for organic electronics and liquid crystal applications. In addition, it may be used in research and development as a starting material to generate arylamine derivatives for various industrial sectors.
