Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 5-fluoro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 1065102-44-4) is a high-purity analytical reference standard with the molecular formula C13H12FNO3 and a molecular weight of 249.24 g/mol.
Based on its molecular formula C13H12FNO3, Ethyl 5-fluoro-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures Ethyl 5-fluoro-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.
