Chemical Structure
Description
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.
4-hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxamide (CAS 68373-65-9), molecular formula C8H19O4PC12H27N and molecular weight 395.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxamide (C8H19O4PC12H27N) is characterized by an amide group, a phosphate ester group, a carboxylic acid 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.
As a certified reference material (CRM), 4-hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
