Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antiseptics and disinfectants. It serves as a building block in the development of certain polymers and resins, enhancing thermal stability and resistance to degradation. Also employed in the preparation of dyes and pigments due to its reactive chlorine groups and aromatic structure. Its derivatives find use in agrochemicals, including herbicides and fungicides, where it contributes to bioactive molecule design. Additionally, it has applications in research laboratories for the development of novel organic compounds and functional materials.
