Trisodium trithiocyanurate

Trisodium trithiocyanurate (CAS 17766-26-6) is an inorganic sodium salt supplied in liquid form, also known commercially as Sevar 2000 and sodium trithiocyanurate. It carries no assigned E-code and is identified under EC number 241-749-5. The compound contains three sulfur-bearing functional groups coordinated with sodium, giving it strong metal-binding and precipitation activity.

In water treatment, trisodium trithiocyanurate removes heavy metals such as mercury, lead, and cadmium by forming highly insoluble metal sulfide precipitates that can be separated through flocculation. In mining and metals processing, it functions as a selective precipitant for precious and base metals in effluent streams, enabling metal recovery and compliance with discharge limits.

The product is supplied as a liquid solution and falls under REACH registration requirements for European markets. It is classified under HS code 29336990 for customs purposes. Buyers should confirm concentration grade and packaging format directly, as these vary by supplier and application requirement.
