Thiourea

Applications

‌I. Medical Applications‌

‌Pharmaceutical Synthesis‌

• Serves as an intermediate in synthesizing thiouracil (an antitumor drug intermediate)‌ and thiourea-based drugs (e.g., methimazole, propylthiouracil)‌.
• Thiourea drugs treat hyperthyroidism by inhibiting thyroid hormone synthesis and assist in preoperative preparation or thyroid crisis management‌.

 ‌II. Industrial Applications‌

2.‌Chemical Production‌

• ‌Organic Synthesis‌:Produces derivatives like methylthiourea and diphenylthiourea‌, rapid-curing agents for epoxy resins, and anion-exchange resins‌.
• Acts as a reducing agent, decolorizer, or antioxidant in plastic stabilizers and photographic material processing‌.
• ‌Catalysts and Additives‌:Catalyzes phthalic anhydride and fumaric acid synthesis‌ and serves as a rubber vulcanization accelerator‌.
• Functions as a bleaching, dyeing, and dechlorinating agent in the textile industry‌.

3.‌Materials and Manufacturing‌

• Enhances electroplating quality by coordinating with metal ions to inhibit discharge‌.
• Extracts precious metals (e.g., gold) in mineral flotation‌ and improves concrete performance as a construction additive‌.

‌III. Agricultural and Laboratory Applications‌

4.‌Agriculture‌

• Boosts nitrogen fertilizer efficiency, promoting plant growth under nutrient-deficient conditions‌.

5.‌Chemical Reagents‌

• Prepares transfer colloids and protonated colloids in laboratories‌, and acts as a reducing agent for vat dyes (e.g., cotton and silk printing)‌.

‌IV. Other Applications‌

6.‌Specialized Uses‌

• Gas leak odorant additive‌.
• Photographic developer and blueprint stabilizer for sharp lines and fade resistance‌
