Chemical Properties
Thiourea is an organic sulfur compound structurally similar to urea, but with sulfur atoms replacing oxygen atoms. This structural difference results in significantly different chemical properties.
Key Characteristics:
- Molecular weight: 76.12 g/mol
- Appearance: White or light yellow crystalline powder, glossy
- Odor: Odorless or slight sulfide odor
- Density: 1.405 g/cm³ (20°C)
- Melting point: 176-178°C (decomposition)
- Solubility: Highly soluble in water (13.7g/100mL at 20°C), slightly soluble in ethanol
- Chemical Safety: Class 6.1 toxic substance
Chemical Behavior
- Acid-base properties: Weakly basic, forms salts with acids
- Reducibility: Can be oxidized by strong oxidants
- Complexation: Forms complexes with metal ions (Ag+, Au+, Cu²+)
- Thermal stability: Decomposes above melting point
- Hydrolysis: Forms urea and hydrogen sulfide under acidic/alkaline conditions
