What is of Ammonium thiocyanate CAS 1762-95-4?
Ammonium thiocyanate: A colourless, soluble crystalline compound,NH4NCS. Ammonium thiocyanate is made by theaction of hydrogen cyanide on ammoniumsulphide or from ammoniaand carbon disulphide in ethanol. Onheating, it turns into its isomerthiourea, SC(NH2)2. Its solutions givea characteristic blood-red colour withiron(III) compounds and so are employedas a test for ferric iron.
