Chemical Structure

Oxalomalic acid (sodium salt) CAS 89304-26-7 chemical structure

Description

Based on its molecular formula C6H3Na3O8, Oxalomalic acid (sodium salt) contains a carbohydrate-derived structure; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Oxalomalic acid (sodium salt) (CAS 89304-26-7), a certified reference material (molecular formula C6H3Na3O8, MW 272.05 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
