Product Application

Used as chemical analysis reagent, polyacrylonitrile fiber spinning solvent, color film washing agent, some plant defoliating agent, etc.
In organic synthesis, it is used to convert halogenated hydrocarbons to the corresponding thiocyanates. For example, isopropyl bromide reacts with sodium thiocyanate in a hot ethanol solution to give isopropyl thiocyanate. Similar reagents include ammonium thiocyanate and potassium thiocyanate.
Sodium thiocyanate is converted to isothiocyanate (S=C=NH) when it encounters acid. After in situ formation, it can react with amines to produce corresponding thiourea derivatives.
Used as solvent for spinning polyacrylonitrile fiber, chemical analysis reagent, color film washing agent, some plant defoliating agent, and airport road weedkiller. Also used in pharmaceutical, printing and dyeing, rubber treatment, black nickel plating and the manufacture of artificial mustard oil.
