Compared with other compounds in its class, the molecular weight of 265.69 g/mol gives Ethyl 6-chloro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 6-chloro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 175134-96-0), molecular formula C13H12ClNO3 and molecular weight 265.69 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 6-chloro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (C13H12ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 6-chloro-8-methyl-4-oxo-1,4-dihydroquinoline-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.
