Thiourea is a widely used organic chemical raw material and fine chemical intermediate, used for the synthesis of sulfonamide drugs (such as sulfathiazole), anti thyroid drugs, anticancer agents, and oral hypoglycemic drugs. Many pharmaceutical molecules contain structural fragments of thiourea, which is also an important intermediate in the synthesis of heterocyclic compounds. As an intermediate for fungicides (such as mixed seed spirit) and herbicides (such as acetochlor and tebuconazole). It can also be used as an insecticide and fungicide to prevent and control fruit tree and crop diseases, and as a plant growth regulator to promote seed germination and root development. Used as a low-temperature vulcanization accelerator for rubber. Used as a flotation agent for metal minerals (such as gold mining), as well as a rust inhibitor for metals. Used as an electroplating additive (especially for gold plating), it can improve the uniformity and brightness of the coating; Electronic grade thiourea can also be used for wafer cleaning and etching processes. Used for synthesizing thiourea formaldehyde resin, flame retardant resin, anion exchange resin, synthetic resin coatings, etc; Used as a catalyst for the production of phthalic anhydride and fumaric acid. Used as a bleaching agent, dyeing assistant, and antioxidant; Used as a processing aid for fabrics, nylon, and polyester fibers. Used as developer and toner, for diazo photosensitive paper, etc. Used as analytical reagents and reducing agents for the detection and determination of metals such as bismuth, rhodium, ruthenium, selenium, lead, tellurium, palladium, etc; Used as a paper processing agent, water treatment agent, and corrosion inhibitor
