Description

Sodium thiocyanate (CAS 540-72-7 ), also known as sodium rhodanide or NaSCN, is an inorganic salt used across chemical manufacturing, textile processing, and life sciences as a reactive intermediate and biocidal agent. Its thiocyanate anion drives reactivity in synthesis, fiber treatment, and antimicrobial applications. In textile manufacturing, NaSCN functions as a solvent and spinning bath component for polyacrylonitrile fiber production. This chemical directly influences fiber quality and process yield during manufacturing. Leather and paper processors use it as a preservation and biocide agent to control microbial growth during wet processing stages. Pharmaceutical and biotech applications rely on sodium thiocyanate as a reagent and buffer component in enzyme assays. It is also utilized in protein denaturation studies and chaotropic salt preparations. Water treatment operations employ it as a catalyst precursor and process chemical in specific treatment chemistries. Sodium thiocyanate is supplied as a white crystalline powder or as an aqueous solution. Solution concentrations typically range from 50% to 58% by weight for industrial use. Technical grade is the most common commercial form, with higher-purity grades available to meet specific requirements. These high-purity options are designed to meet pharmaceutical and laboratory specifications. Bulk quantities are standard for industrial buyers, with smaller packaging available for research and specialty use. Contact us for supply of Sodium thiocyanate Request Quote
