Product Overview

Potassium Metavanadate 98% Extra Pure (CAS No. 13769-43-2) is an inorganic vanadium(V) salt containing the metavanadate oxyanion. Vanadium(V) oxyanions display pH- and concentration-dependent condensation and coordination behaviour, allowing metavanadate to serve as a useful precursor for oxovanadium compounds, coordination complexes and vanadium-containing materials. The submitted identity corresponds to potassium metavanadate rather than another potassium vanadate stoichiometry.

The Extra Pure grade is intended for inorganic synthesis, coordination chemistry and materials-oriented research requiring a source of vanadium in the +5 oxidation state. Potassium metavanadate is useful as a starting material for preparation of oxovanadium(V) complexes and other vanadate-containing systems. 

Typical Applications

• Precursor for synthesis of vanadium(V) coordination complexes.
• Preparation of oxovanadium and dioxovanadium compounds.
• Source of metavanadate in inorganic reaction studies.
• Preparation of vanadium-containing materials and oxide precursors.
• Investigation of vanadate condensation, protonation and coordination equilibria.
• General research on vanadium(V) redox and structural chemistry.

Common Synonyms

• Potassium vanadate(V)
• Potassium trioxovanadate(V)
• Potassium meta-vanadate
• Potassium metavanadate

Storage Conditions

Store tightly closed and dry to prevent contamination and uncontrolled changes associated with absorbed moisture. Protect from reducing contamination so that the intended vanadium(V) oxidation state is preserved during storage and reagent preparation.
