Brief introduction

Thiourea is an organic sulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2.

Its structure is similar to urea (H 2 N−C(=O)−NH 2), 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)(NH 2), SC(NHR) 2, etc

Riel Chemical's thiourea manufacturing process

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.

1. Chemical industry
Synthesis intermediates: thiourea is an important intermediate in many organic synthesis reactions, which can be used to synthesize thiazole, urea, sulfhydryl compounds, etc.
