Sodium metavanadate

Sodium metavanadate (CAS 13718-26-8), also referenced commercially as sodium trioxovanadate and NaVO3, is an inorganic vanadium salt used as a catalyst precursor and biocidal agent.

Where is Sodium metavanadate used?

• Water treatment: corrosion inhibitor and biocide
• Cooling systems and pipelines: protection from microbial fouling and metal degradation
• Mining and hydrometallurgy: catalyst precursor in oxidation processes, including recovery and refining of non-ferrous metals
• Pharmaceutical and biotechnology research: vanadate solutions inhibit phosphatase enzymes in cell biology assays
• Catalyst manufacturing: vanadium source for mixed-oxide catalysts in sulfuric acid production and other oxidation reactions
• It also serves as a practical source of vanadate ions where controlled vanadium delivery is required.

Good to know: Analytical applications may require specific quality standards such as ACS or USP depending on the final use.

Commercial specifications

• Technical grade is the standard commercial form, with higher-purity grades available for research
• Packaging typically ranges from small laboratory quantities to bulk industrial supply
