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.
CATO supplies 1-(3,5-Dimethylphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (CAS 1266894-69-2), a certified reference material (molecular formula C14H13NO3, MW 243.26 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3,5-Dimethylphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (C14H13NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(3,5-Dimethylphenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid 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.
