Potassium thiocyanate

Potassium thiocyanate (CAS 333-20-0) is an inorganic salt used in industrial and laboratory processes. Also marketed as Rhocya, potassium rhodanide or potassium sulfocyanate.

Where is Potassium thiocyanate used?

• Water treatment: biocide and corrosion inhibitor controlling microbial growth in industrial cooling and process water systems
• Pharmaceutical manufacturing: reagent in synthesis pathways
• Analytical testing: reference standard
• Biotechnology and life sciences: chaotropic agent in protein denaturation and cell lysis buffers
• Organic synthesis: catalyst precursor where thiocyanate coordination chemistry drives reaction selectivity
• It also serves as a reagent and biocidal agent.

Commercial specifications

• Technical grade and high-purity grades meeting pharmaceutical and analytical specifications
• USP and ACS requirements where specified
• Bulk quantities for industrial procurement; smaller packaging for laboratory use
