Physical and Chemical Properties of Thiourea

Molecular weight: 76.12 g/mol
Appearance: White or light yellow crystalline powder, glossy
Odor: Odorless or slightly sulphide odor
Density: 1.405 g/cm³ (20°C)
Melting point: 176-178°C (decomposition)
Chemical Safety: Class 6.1 toxic substances
Solubility: Water: soluble (about 13.7g/100 mL, 20°C); Ethanol: slightly soluble
Acid base: Weakly basic, can react with acids to form salts
Reducibility: Can be oxidized by oxidants (hydrogen peroxide, potassium permanganate)
Complexation: Forms complexes with metal ions (Ag+, Au+, Cu²+)
Thermal stability: Decomposes above melting point, producing ammonia and hydrogen sulfide
Hydrolysis reaction: Produces urea and hydrogen sulfide under acidic/alkaline conditions

Thiourea Industry Status

Current Situation of Industry

Production and supply: Global production concentrated in China, India, Japan, and USA. China is largest producer/exporter.
