Used primarily in organic synthesis as an intermediate for the production of dyes, pigments, pharmaceuticals, and agrochemicals such as pesticides and fungicides. It plays a role in the development of naphthalene-based compounds, which are essential in creating colorants for textiles and inks. Additionally, it is utilized in research for studying chemical reactions involving naphthalene derivatives and developing new drugs in pharmaceuticals. Its chlorinated structure makes it valuable for further functionalization in the synthesis of complex organic molecules. It can also serve as an intermediate in producing additives for various industries.
