Description
Sodium metavanadate (CAS 13718-26-8, EC 237-272-7) is an inorganic vanadium salt commonly referenced as NaVO3 or sodium vanadate. It carries no assigned E-code. The compound is classified under HS code 28419000 and falls within the Salts & Minerals category.
In water treatment, sodium metavanadate acts as a corrosion inhibitor by forming a protective oxide layer on metal surfaces, reducing pipe degradation. In catalysis, it serves as an oxidation catalyst in chemical synthesis and industrial processes. Biotechnology and pharmaceutical researchers also use it as a phosphatase inhibitor in cell biology assays.
Sodium metavanadate is supplied as a powder and is subject to REACH registration requirements within the EU. Buyers should confirm grade specifications against intended application, as purity requirements differ between industrial and laboratory uses. Standard packaging formats vary by supplier; technical and reagent grades are typically available.
