Sodium thiocyanate (NaSCN) is an inorganic salt primarily used as a solvent in gold and silver extraction, a reagent in chemical synthesis, and in the production of pharmaceuticals and dyes. It also serves as a corrosion inhibitor and in the manufacturing of certain plastics. It is also a common starting material for preparing other thiocyanate compounds and is used as a stabilizing agent. This chemical has a CAS number of 540-72-7, a molecular weight of 81.07 g/mol, and is stored at ambient conditions. It carries a signal word of "Danger" due to its hazardous properties.
