This product is flammable, toxic, insoluble in water, slightly soluble in cold ethanol, and easily soluble in organic solvents such as ether, benzene, etc. It is non-corrosive, easily tends to sublimation, and has pungent camphor odor and stable chemical properties.
It is raw material of organic synthesis, used in the synthesis of dyes (bright red GG and red 3GL, active yellow and red RC) and pesticide intermediates, and used as fumigation insecticide, mothproofing agent of fabric, mildew inhibitor, and air deodorant. 65% - 70% of the product is used in manufacture of mothball, and a small amount of them is used in manufacture of extreme pressure lubricants and corrosion inhibitors. It can also be used in medicinal industry, and used as solvent and mutagen. In addition, it is also the raw material for synthesizing the sixth largest engineering plastics, polyphenylene sulfide.
