Potassium cobalt(III) nitrite CAS 13782-01-9 chemical structure

Description

Potassium cobalt(III) nitrite (CAS 13782-01-9) is a high-purity analytical reference standard with the molecular formula CoKN6O12K2 and a molecular weight of 452.26 g/mol.

Potassium cobalt(III) nitrite (CoKN6O12K2) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
