Purpose:

Imidazole is an important fine chemical raw material, which is mainly used in the synthesis of medicine and pesticide and epoxy resin curing agent. It is used as pesticide raw material, synergist of boric acid preparation and preparation of insecticide and bactericide. As an epoxy resin curing agent, it can improve the mechanical properties such as bending, tension and compression of products, improve the electrical properties of insulation and improve the chemical properties of chemical resistance. It is widely used in computers and electrical appliances. It is used as imidazole antifungal drugs in medicine. It is one of the main raw materials of diclofenazole, Econazole, ketoconazole, clotrimazole and other drugs. It can be used as a rust inhibitor of copper for printed circuit boards and integrated circuits. It is also used as raw materials and organic synthetic intermediates of urea formaldehyde resin curing agent, photographic drugs, adhesives, coatings, rubber vulcanizing agent and antistatic agent. It is also widely used as preservative of fruits.
