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. Его растворы придают характерный кроваво-красный цвет соединениям железа (III) и поэтому используются в качестве теста на трехвалентное железо.
