Thiocynnate

Ammonium thiocyanate is an inorganic compound with the formula NH4SCN.Ammonium thiocyanate is used in the manufacture of herbicides, thiourea, and transparent artificial resins; in matches; as a stabilizing agent in photography; in various rustproofing compositions; as an adjuvant in textile dyeing and printing; as a tracer in oil fields; in the separation of hafnium from zirconium, and in titrimetric analyses.

Sodium thiocyanate is the chemical compound with the formula NaSCN. This colourless deliquescent salt is one of the main sources of the thiocyanate anion. As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals.[1] Thiocyanate salts are typically prepared by the reaction of cyanide with elemental sulfur:
