Thiourea (CAS 62-56-6) is an organosulfur compound (CH4N2S). its principal uses are as an intermediate in producing thiourea dioxide for wool and textile processing, in ore (precious-metal) leaching, in diazo copy papers, as a catalyst in fumaric-acid synthesis, and in cleaning silver and copper.
Frequently Asked Questions
What is thiourea used for?
Thiourea (CH4N2S, CAS 62-56-6) is an organosulfur compound used mainly as an intermediate for thiourea dioxide reducing/bleaching agents in wool and textile processing. It also serves as a leaching agent for ores and precious metals, a component of diazo copy papers, a reagent and catalyst in chemical synthesis, and in cleaning silver and copper. We supply it in bulk as an industrial intermediate.
What is the smell of thiourea?
Thiourea is typically described as having a faint or bitter odor and is supplied as a white crystalline solid. Detailed physical and organoleptic characteristics for a given lot are documented on the SDS and CoA.
What is the chemical formula and structure of thiourea?
Thiourea has the molecular formula CH4N2S (CAS 62-56-6). It is the sulfur analog of urea, with a thiocarbonyl group (C=S) bonded to two amino (NH2) groups. Full identity data is provided on the CoA.
How is thiourea shipped under DOT rules?
Thiourea is assigned UN 2811. Classification, packing group, and labeling are detailed on the SDS and must follow current DOT/IATA/IMDG requirements for the chosen mode. We provide compliant shipping documentation with each order.
What is the cost of bulk thiourea and how is it supplied?
Thiourea pricing is quote-based and varies with grade, volume, and packaging. It is supplied as a crystalline solid in bulk industrial quantities. Submit a bulk quote request with your target volume to receive current pricing, CoA, and SDS.
