ammonium thiocyanate: A colourless, soluble crystalline compound,NH4NCS. It 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.

Colorless deliquescent crystals made by boiling an aqueous solution of ammonium cyanide with sulfur or polysulfides. It must be kept in a well-sealed container. The principal use for ammonium thiocyanate was in gold-toning formulas, but it was also used in a 5 percent solution to dissolve gelatin in overexposed carbon prints.
