Potassium thiocyanate, also known as potassium thiocyanate, is a single potassium salt of thiocyanate with the chemical formula KSCN. It has a relative molecular weight of 97.18 and a density of 1.9g/cm3. The appearance is colorless to white hygroscopic crystals, easily soluble in water, as well as solvents such as alcohol and acetone, with a boiling point of 500 ℃ (decomposition) and a melting point of 173 ℃. When potassium thiocyanate melts, it can be converted into brown, green, and blue colors, and when cooled, it returns to colorless. -Stable at 29.5~6.8 ℃, turns blue when heated to about 430 ℃, turns colorless again after cooling, and cools down due to a large amount of heat absorption. Half water can be obtained at low temperature, and it decomposes when heated to 500 ℃. When encountering iron salts, blood red thiocyanate iron is generated, but it does not react with ferrous salts. Reacts violently with strong oxidants.

The production methods of potassium thiocyanate include potassium cyanide method, ammonium thiocyanate lime milk method, and ammonium thiocyanate potassium carbonate method. It is widely used in the electroplating industry as a stripping agent and also as a refrigerant. Used as an early strength agent in concrete admixtures, it can also be used in the dyeing industry, photography industry, pesticides, and steel analysis. It can be used for the synthesis of resins, pesticides and insecticides, pigment synthesis, and the production of photographic assistants.
