Chemical name for nh4scn

  Ammonium thiocyanate, also known as ammonium thiocyanate, ammonium thiocyanate, colorless lustrous monoclinic crystal system sheet or columnar crystal, chemical formula NH4SCN, molecular weight 76.12.
  Under the action of sunlight, the solution is red, and when heated to about 140 ° C, thiourea is formed, and at 170 ° C, it is decomposed into ammonia, carbon disulfide and hydrogen sulfide. Easy deliquescence, should be sealed storage. Uses: Mainly used in photography, dyes, pesticides and other industries, for the separation of antibiotics, printing and dyeing diffusion agent, organic synthesis polymerization catalyst, chemical analysis, but also used in zinc coating, plating additives and so on.

  Main Uses: 

  Potassium thiocyanate is mainly used in the production of synthetic resins, insecticides and fungicides, mustard oil, thiourea and drugs, also used as a chemical reagent, is a common indicator of trivalent iron ions, after addition to produce blood red flocculation complex. Preparation of thiocyanate solution, determination of trivalent iron, copper and silver, urine test, tungsten chromogenic agent, indicator of legal capacity of titanium. A refrigerant. Photographic thickener. Test function: This product is used to test the presence of iron ions in general chemical experiments. If iron ions are present, the solution becomes red when it forms a complex (not considered as precipitation). And can be paired with chlorine water to detect ferrous ions indirectly.
