Chemical Structure
Description
CATO supplies Ethyl 5,7-dimethyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 93514-84-2), a certified reference material (molecular formula C14H15NO3, MW 245.27 g/mol) for analytical method development and quality control.
Ethyl 5,7-dimethyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (C14H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Ethyl 5,7-dimethyl-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.
