Description
Sodium Thiocyanate (CAS 540-72-7, EC 208-754-4), also known as sodium rhodanide or sodium rhodanate, is an inorganic salt with the formula NaCHNS. It carries no assigned E-code. The compound is commercially referenced under trade names including Haimased and Natriumrhodanid.
In textile processing, Sodium Thiocyanate acts as a solvent and swelling agent for cellulose fibres, enabling controlled fibre dissolution. In pharmaceutical and biotechnology applications, it functions as a buffering salt to stabilise pH in biological media and enzyme assays. Water treatment operations use its thiocyanate anion as a catalyst in specific oxidation reactions targeting contaminants.
Sodium Thiocyanate is supplied as a white crystalline powder in technical and reagent grades, with pharmaceutical-grade material available to Ph.Eur. standards. It falls under REACH regulation (EC 1907/2006) and is classified under HS code 28429011. Standard packaging includes 25 kg bags and bulk quantities on request.
