Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Ethyl 4-(4-chlorophenyl)-1-(2-ethoxy-2-oxoethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carboxylate (CAS 338966-57-7), a certified reference material (molecular formula C19H22ClNO5, MW 379.83 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 4-(4-chlorophenyl)-1-(2-ethoxy-2-oxoethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carboxylate (C19H22ClNO5) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures Ethyl 4-(4-chlorophenyl)-1-(2-ethoxy-2-oxoethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-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.
