Chemical Structure

Potassium tetroxalate CAS 127-96-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium tetroxalate.

Potassium tetroxalate (CAS 127-96-8), molecular formula C2HO4KH and molecular weight 129.13 g/mol, is a CATO reference standard with documented purity and traceability.

Potassium tetroxalate (C2HO4KH) contains a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
