Hydrogen cyanide is an intermediary chemical in the manufacture of other chemical products including: adiponitrile, acetone cyanohydrin, sodium cyanide, methionine, chelating agents, cyanuric chloride, nitrilotriacetic acid and salts, and other chemical products such as potassium cyanide. Electroplating is the primary end use for sodium and potassium cyanide in Massachusetts.
Cyanide and cyanide compounds are designated as Higher Hazard Substances under TURA, which lowers the reporting threshold to 1,000/lb/year, effective January 2016.
