Potassium metavanadate CAS 13769-43-2 chemical structure

Description

CATO supplies Potassium metavanadate (CAS 13769-43-2), a certified reference material (molecular formula O3VK, MW 138.04 g/mol) for analytical method development and quality control.

Potassium metavanadate (O3VK) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
