Chemical Structure
Description
As a certified reference material (CRM), 1-(3,4-Dichloro-benzyl)-2-oxo-1,2-dihydro-pyridine-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.
CATO supplies 1-(3,4-Dichloro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (CAS 64488-03-5), a certified reference material (molecular formula C13H9Cl2NO3, MW 298.12 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3,4-Dichloro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (C13H9Cl2NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
