Chemical Structure

Sodium 2-oxomalonate CAS 7346-13-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 139.02 g/mol gives Sodium 2-oxomalonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium 2-oxomalonate (CAS 7346-13-6), molecular formula C3O5Na and molecular weight 139.02 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium 2-oxomalonate (C3O5Na) is characterized by a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
