Description
CATO supplies Ethyl 7-chloro-6-(difluoromethoxy)-1-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 1443288-56-9), a certified reference material (molecular formula C15H14ClF2NO4, MW 345.73 g/mol) for analytical method development and quality control.
Ethyl 7-chloro-6-(difluoromethoxy)-1-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (C15H14ClF2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Ethyl 7-chloro-6-(difluoromethoxy)-1-ethyl-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.
