3-Hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-4-carboxylic acid (CAS 1378791-48-0) is a high-purity analytical reference standard with the molecular formula C7H7NO4 and a molecular weight of 169.13 g/mol.
The molecular framework of 3-Hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-4-carboxylic acid (C7H7NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
