• 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

• 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)

• 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

• 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

• 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

• Mature production technology: Over 20 years of experience in nitric acid production, with stable quality products that exceed national standards

• High standard quality control: Products exceed national excellent product standards and have obtained EU REACH certification
• Environmental protection and sustainable development: Focus on green manufacturing and resource recycling
