Ammonium thiocyanate CAS 1762-95-4

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. 它的解决方案givea特征血红色的withiron(III)化合物，因此是employedas一个测试铁铁。
