Chemical Structure
Description
As a certified reference material (CRM), 5-Chloro-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-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.
5-Chloro-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxylic acid (CAS 339024-23-6), molecular formula C14H9ClF3NO3 and molecular weight 331.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxylic acid (C14H9ClF3NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
