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 thioprefix implies). The properties of urea and thiourea are very different. Thiourea is an organic synthesis reagent. Thiourea is 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: | Thiourea is weakly basic and can react with acids to form salts |
| Reducibility: | Thiourea has a certain reducibility and can be oxidized by oxidants (such as hydrogen peroxide, potassium permanganate) |
| Complexation: | Thiourea forms complexes with metal ions (e.g. Ag+, Au+, Cu²+) and is often used in metal extraction and electroplating industries |
| Thermal stability: | When heated above the melting point, it decomposes, producing ammonia, hydrogen sulfide and other gases |
| Hydrolysis reaction: | Hydrolysis under acidic or alkaline conditions to produce urea and hydrogen sulfide |
