Product Description

High Purity Potassium Thiocyanate with CAS No. 333-20-0

Product Overview

Potassium thiocyanate, formula KSCN, also known as potassium thiocyanate, English Potassium Thiocyanate, is a colorless monoclinic crystal. Relative density 1.886. Melting point is about 172.3°C. Soluble in water and cooled by a large amount of heat absorption, it is also soluble in alcohol (ethanol) and acetone. At low temperatures, hemihydrate crystals (KSCN.0.5H2O) are obtained, are stable at -29-6.8°C, and glow to a temperature of about 430, but then return to colorless after they cool. Decomposes when heated to 500. It is Fe3+ (iron salt) which generates the red-colored iron thiocyanate iron ion FeSCN2+ (iron thiocyanate). It is a very sensitive method for detecting Fe3+ ions, and can eliminate all other metal ions known to date. It does not react with ferrous salts. Deliquescence should be sealed and stored. There is low toxicity. However, potassium cyanide is a highly toxic substance, and the country has already restricted production.
