Thiourea is an organosulfur compound with the formula SC(NH2)2. It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom, but the properties of urea and thiourea differ significantly. Thiourea is a reagent in organic synthesis. "Thioureas" refers to a broad class of compounds with the general structure (R1R2N)(R3R4N)C=S. Thioureas are related to thioamides, e.g. RC(S)NR2, where R is methyl, ethyl, etc.
Thiourea is mainly used as a raw material for the synthesis of sulfathiazole, methionine and other drugs, and can also be used as a raw material for dyes and dyeing auxiliaries, resins and molding powders, and can also be used as a vulcanization accelerator for rubber, a flotation agent for metal minerals, a catalyst for the production of phthalic anhydride and fumaric acid, and as a metal rust inhibitor. In terms of photographic materials, it can be used as a developer and toner, and can also be used in the electroplating industry. Thiourea is also used in diazo photosensitive paper, synthetic resin coatings, anion exchange resins, germination promoters, fungicides and many other aspects. Thiourea is also used as a fertilizer. Used in the manufacture of drugs, dyes, resins, molding powder, rubber vulcanization accelerator, metal mineral flotation agents and other raw materials.
Thiourea also has broad application prospects in petrochemical and pharmaceutical chemicals. Many pharmaceutical molecules contain thiourea structural fragments, and thiourea is also an important intermediate for 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, it is used to produce thiourea derivatives such as methyl thiourea, diethyl thiourea, diphenyl thiourea, urea sulfur dioxide, and the catalyst for producing phthalic anhydride and fumaric acid. Used to prepare epoxy resin fast curing agent, synthetic resin coating, anion exchange resin. It can also be used as a toughening agent for melamine formaldehyde resin adhesives. In terms of photographic materials, thiourea can be used as a developer and toner, azo photosensitive paper reducing agent. It is also used as rubber vulcanization accelerator, metal mineral flotation agent, dye dyeing aid, textile, nylon and polyester fiber processing aid, paper treatment agent, electroplating additive, metal rust inhibitor, pesticide, fertilizer and so on.

Thiourea Mainly used as intermediate in pharmaceutical, sulfuration accelerator in rubber industry, floatation agent in mining, as well as treatment agent in fabrics and paper, auxiliary in printing and dyeing and petroleum. It can also be used in metallurgy, electroplating and pesticide.
Thiourea is the main raw material for producing sulfur dioxide urea. In medicine (sulfathiazole, methylthiouracil, tetrazolidin, nidazolidin, fluorouracil), pesticides (insecticidal, bactericidal, acaricidal, herbicidal, virus control, etc.), fertilizer (nitrogen fertilizer synergist), silk industry, agriculture, metal processing and so on.
Thiourea is the intermediate of fungicide, herbicide acetochlor, teretoxazine, etc., is also the raw material of thiaminethiazole, and can be used as the raw material of dyes, resins, molding powder, and can also be used as a vulcanization accelerator of rubber, flotation agent of metal minerals.
Used as raw material for dyes and dyeing AIDS, resins and molding powders. It can also be used as a vulcanization accelerator for rubber, a flotation agent for metal minerals, a catalyst for making phthalic anhydride and fumaric acid, and as a metal rust inhibitor. In the photographic material Chemicalbook, it can be used as a developer and toner. It can also be used in electroplating industry. Thiourea is also used in diazo photosensitive paper, synthetic resin coatings, anion exchange resins, germination promoters, fungicides and many other aspects. Thiourea is also used as a fertilizer..
