Products meets GB/8218-2018:

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 thio prefix 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.

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 is used as an additive in diazo paper, photosensitive copy paper, and almost all other types of copy paper. It is also used for toning silver gelatin photo prints (see tan toning). Thiourea is used in bright and semi-bright plating processes for Clifton-Phillips and Beaver. It is also used with tin chloride in electroless tin plating solutions for copper printed circuit boards.

Thiourea (usually used as a hydrogen bond donor catalyst) is used in thiourea organic catalysis research topics. It has been found that thiourea is a stronger hydrogen bond donor (i.e. more acidic) than urea.
