Physicochemical 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 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
Thiourea Applications
Chemical Industry
Reducing agent: Commonly used as a reducing agent, especially in the reduction reaction of metal ions
Coordination agent: Forms stable complexes with a variety of metal ions for metal separation and purification
Organic synthesis: Important intermediate for the synthesis of many organic compounds (such as thioamides, heterocyclic compounds)
Electroplating Industry
Plating additive: Used in electroplating solution to improve the gloss and uniformity of the coating, especially in the plating process of silver, copper, zinc and other metals
Corrosion inhibitor: Inhibits the corrosion of the metal surface and extends the life of the coating
Medical Field
Drug synthesis: Intermediate in the synthesis of certain antibiotics, anti-thyroid drugs (such as propylthiouracil), and anti-cancer drugs
Antioxidants: Has certain antioxidant properties and can be used in pharmaceutical preparations
Agriculture
Fungicides and insecticides: Can be used to prepare certain pesticides for the control of crop diseases and pests
Plant growth regulators: In some cases, can promote plant growth or regulate plant physiological processes
