Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Propanedioic acid, 2-methyl-, sodium salt (1:2) (CAS 53007-37-7), molecular formula C4H4Na2O4 and molecular weight 162.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Propanedioic acid, 2-methyl-, sodium salt (1:2) (C4H4Na2O4) is characterized by a carbohydrate-derived structure. 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).
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.
