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-(4-Bromophenyl)-4-methyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid (CAS 39818-81-0), a certified reference material (molecular formula C13H10BrNO3, MW 308.13 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Bromophenyl)-4-methyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid (C13H10BrNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 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).
CATO manufactures 1-(4-Bromophenyl)-4-methyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
