Chemical Structure

Sodium 2-Oxobutyrate CAS 2013-26-5 chemical structure

Description

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.

Sodium 2-Oxobutyrate (CAS 2013-26-5) is a high-purity analytical reference standard with the molecular formula C4H5O3Na and a molecular weight of 124.07 g/mol.

Sodium 2-Oxobutyrate (C4H5O3Na) contains a carboxylic acid group, a hydroxyl 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.
