Potassium thiocyanate ACS is a versatile inorganic salt widely used as a titrant for silver in Volhard titrations, in analytical chemistry for complexation reactions, and in the production of synthetic fibers. It also serves in textile printing and dyeing, as a photographic intensifier, in making mustard oil, and as a contact fungicide for greenhouse crops. It is also employed in electroplating and as a reagent in laboratory tests. This high-purity reagent meets ACS specifications, with a CAS number of 333-20-0, molecular formula KSCN, and a molecular weight of 97.18. It is stored at ambient conditions but requires careful handling due to its hazardous nature, marked with a signal word of "Danger." Molekula supplies Potassium thiocyanate ACS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
