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. 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
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
Chemical Behavior
- 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 when heated above melting point, producing ammonia and hydrogen sulfide
- Hydrolysis: Hydrolyzes under acidic/alkaline conditions to produce urea and hydrogen sulfide
Safety Information
Corrosiveness Analysis
- Weak acidity/reducing property: Aqueous solution is weakly acidic (pH≈6-7), minimal corrosiveness to common metals but may affect copper with long-term contact
- Reaction with oxidants: Mixing with strong oxidants may produce irritating gases (sulfur dioxide)
Major Safety Risks
- Toxicity: Oral ingestion, inhalation or skin contact may pose health risks (potential carcinogen classified as IARC Group 3)
- Irritation: May irritate eyes, skin and respiratory tract, cause allergic reactions
- Environmental risk: Degradation may produce toxic sulfur compounds requiring professional waste treatment
Safety Usage Suggestions
- Wear gloves, goggles and dust masks during handling
- Ensure good ventilation, especially when heating or preparing solutions
- Store in sealed containers in cool, dry places away from oxidants and food
