Sodium thiocyanate

Sodium thiocyanate (CAS 540-72-7), also known as sodium rhodanide or NaSCN, is an inorganic salt used as a reactive intermediate and biocidal agent.

Where is Sodium thiocyanate used?

• Chemical manufacturing: reactive intermediate via the thiocyanate anion
• Textile processing: solvent and spinning bath component for polyacrylonitrile fiber production
• Leather and paper: preservation and biocide agent controlling microbial growth during wet processing
• Pharmaceutical and biotech: reagent and buffer component in enzyme assays
• Water treatment: catalyst precursor and process chemical
• It is also utilized in protein denaturation studies and chaotropic salt preparations.

Commercial specifications

• Aqueous solution concentrations typically 50% to 58% by weight for industrial use
• Technical grade most common; higher-purity grades meet pharmaceutical and laboratory specifications
• Bulk quantities standard for industrial buyers; smaller packaging for research and specialty use
