Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[2-(2-chlorophenoxy)ethyl]-6-oxo-1,6-dihydropyridine-3-carboxylic acid.
1-[2-(2-chlorophenoxy)ethyl]-6-oxo-1,6-dihydropyridine-3-carboxylic acid (CAS 1423026-82-7), molecular formula C14H12ClNO4 and molecular weight 293.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[2-(2-chlorophenoxy)ethyl]-6-oxo-1,6-dihydropyridine-3-carboxylic acid (C14H12ClNO4) 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 the protonation state of its nitrogen-containing groups, 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.
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 manufactures 1-[2-(2-chlorophenoxy)ethyl]-6-oxo-1,6-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.
