CH4N2S Highly Purity Sulfourea Thiourea For Gold Plating Tin Plating Solution
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 (as the thioprefix implies). The properties of urea and thiourea are very different. Thiourea is an organic synthesis reagent. Thiourea is a broad class of compounds with the formula SC(NHR)(NH2), SC(NHR)2, etc.

Physical and Chemical Properties of Thiourea
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
