Brief Introduction
Thiourea is an organic sulfur compound with the formula SC(NH2)2 and the structure H2N−C(=S)−NH2. Its structure is similar to urea (H2N−C(=O)−NH2), but oxygen atoms are replaced by sulfur atoms (as the thio prefix implies). The properties of urea and thiourea are very different. Thiourea is an organic synthesis reagent and a broad class of compounds with the formula SC(NHR)(NH2), SC(NHR)2, etc.
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 in water (about 13.7g /100 mL, 20°C); Ethanol: slightly soluble in ethanol
Acid base: Weakly basic, can react with acids to form salts
Reducibility: Can be oxidized by oxidants (such as hydrogen peroxide, potassium permanganate)
Complexation: Forms complexes with metal ions (e.g. Ag+, Au+, Cu²+)
Thermal stability: Decomposes when heated above melting point
Hydrolysis reaction: Produces urea and hydrogen sulfide under acidic or alkaline conditions
