Chemical Structure
Description
Ethyl 4,5-dichloro-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate (CAS 853105-72-3) is a high-purity analytical reference standard with the molecular formula C9H9Cl2NO3 and a molecular weight of 250.08 g/mol.
The molecular framework of Ethyl 4,5-dichloro-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate (C9H9Cl2NO3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 4,5-dichloro-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate 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.
