Product application:
Thiourea has a wide range of applications in petrochemicals and pharmaceuticals, many pharmaceutical molecules contain structural fragments of thiourea, and thiourea is also an important intermediate in the synthesis of heterocyclic compounds. For example, many oral hypoglycemic drugs and antithyroid drugs on the market belong to thiourea molecules. In addition, thiourea compounds have good insecticidal activity and are widely used in the field of pesticides. In organic synthesis, they are used to manufacture thiourea derivatives such as methylthiourea, diethylthiourea, diphenylthiourea, thiourea dioxide and so on. It is also used in the preparation of epoxy resin fast curing agent, synthetic resin coating, anion exchange resin. It can also be used as a toughening agent for melamine formaldehyde resin adhesive. In photographic materials, thiourea can be used as a developer and toner, azo-sensitive paper reducing agent. It is also used as vulcanization accelerator for rubber, flotation agent for metal minerals, dyeing and dyeing auxiliaries, processing auxiliaries for fabrics, nylon and polyester fibers, paper treatment agent, electroplating additives, metal antirust agent, pesticides, fertilizers and so on.
