    Physicochemical property

    Molecular weight: 76.12 g/molAppearance: 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 use

    1. Chemical industry
    Reducing agent: Thiourea is commonly used as a reducing agent, especially in the reduction reaction of metal ions.

    Coordination agent: It can form stable complexes with a variety of metal ions for metal separation

    and purification.

    Organic synthesis: Thiourea is an important intermediate for the synthesis of

    many organic compounds (such as thioamides, heterocyclic compounds).

    2. Electroplating industry
    Plating additive: Thiourea is 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: It can inhibit the corrosion of the metal surface and extend the life of the coating.

    3. The field of medicine
    Drug synthesis: Thiourea is an intermediate in the synthesis of certain antibiotics,

    anti-thyroid drugs (such as propylthiouracil), and anti-cancer drugs.

    Antioxidants: Thiourea has certain antioxidant properties and can be used in pharmaceutical preparations.

    4. Agriculture
    Fungicides and insecticides: thiourea can be used to prepare certain pesticides for the control of crop diseases and pests.

    Plant growth regulators: In some cases, thiourea can promote plant growth or regulate plant physiological processes.
