Product Description

Thiourea CAS 62-56-6
Thiourea (thiocarbamide) is a versatile organosulfur reagent and intermediate used in chemical synthesis, metal-complexing applications, accelerators for rubber processing, and laboratory analytical chemistry. It is supplied in technical and reagent grades with documented batch COA and must be handled per SDS and EHS requirements.

  • Applications
    Chemical intermediate
    Thiourea is employed as a building block for the synthesis of thiourea derivatives, heterocyclic compounds and specialized fine chemicals used across pharmaceuticals and agrochemicals.
  • Rubber processing accelerator
    Used in the formulation of vulcanization accelerators and rubber chemicals to improve cure rates and product properties in selected elastomer systems.
  • Metal complexing and plating chemistry
    Applied as a complexing or additive agent in certain metal-finishing and electroplating processes and in analytical chemistry for metal speciation.
  • Laboratory reagent and analytical chemistry
    Used as a standard reagent in organic and inorganic synthesis, as a reducing or sulfur-donating reagent and as a component in analytical methods.
  • Photographic and photographic-chemistry applications
    Used in selected photographic and imaging chemistries and as a reagent in specialty photographic processing formulations.
  • Research and specialty applications
    Used in R&D for sulfur-transfer, condensation and heterocycle-forming reactions in academic and industrial research.
