Chemical Structure
Description
The occurrence of 5-Chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid (CAS 339024-74-7), a certified reference material (molecular formula C13H9Cl2NO3, MW 298.12 g/mol) for analytical method development and quality control.
5-Chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid (C13H9Cl2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
