Description

Compared with other compounds in its class, the molecular weight of 245.23 g/mol gives 1-(2-Methoxyphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(2-Methoxyphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (CAS 1267237-99-9), a certified reference material (molecular formula C13H11NO4, MW 245.23 g/mol) for analytical method development and quality control.

1-(2-Methoxyphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (C13H11NO4) contains a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
