Synonyms: Ammonium Rhodanide; Ammonium Rhodantate; Ammonium Rhodonide; Ammonium sulfocyanate; Ammonium Sulfocyanide; Ammonium thiocyanate; ATC; Thiocyanic acid, ammonium salt; Trans-aid; Properties: NH4SCN, a colorless crystalline or column crystal that is soluble in water, methanol, ethanol, pyridine, acetone & ammonia and insoluble in ethyl acetate, methyl chloride and chloroform; At 140C bring thiourea. Melts at 149.6C...Thermal decomposition at 170 C may produce highly toxic fumes of hydrogen cyanide, hydrogen sulfide and toxic oxides of nitrogen, sulfur, and carbon. Usage: General: Mainly in pharmaceuticals, pesticide, textile, electroplating, photography, water tracer in oil fields, thinning agent, as intermediate for metal thiocyanates etc. Textile: Printing, dyeing and finishing operations accelerator in fixing baths Pesticide: Raw material for the production of a number of herbicides and fungicides Photographic: Stabilizer, accelerator, etc. Metal finishing: Plating, flotation agent. As intermediate for metal thiocyanates (NaSCN, KSCN, CuSCN, Ca(SCN)2 ). Storage: Store away from incompatible substances. Keep in a tightly closed bags. Store in a cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids bases and oxidants.
