As a dye intermediate, it serves as a key precursor for synthesizing anthraquinone and azo dyes, applied in textile, printing, and coating industries. In pesticide fungicides, it can be converted into 2,3-dichloro-1,4-naphthoquinone for controlling diseases in vegetables, grains, and other crops. As a polymer regulator, it is used in the free radical polymerization of synthetic rubber and resins to regulate molecular weight and reaction rate. In medicine and bioactivity, it has the potential to inhibit monoamine oxidase (MAO) and DNA topoisomerase...
