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
