Potassium thiocyanate is used in the preparation of ethylenesulfide, lead thiocyante, which is used in the conversion of acyl chloride to thiocyanates. It is also used in solid state NMR of heavy-metal nuclei which results in the preparation of several mercury-thiocyanate and selenocyanate compounds as potential models. It finds application in cosmetic and personal care product formulations as a skin conditioning agent. It is also used in moisturizers and oral care products.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
