Chemical Structure
Description
The occurrence of Ethyl 1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 1513-07-1) is a high-purity analytical reference standard with the molecular formula C14H14FNO3 and a molecular weight of 263.26 g/mol.
Based on its molecular formula C14H14FNO3, Ethyl 1-ethyl-6-fluoro-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 263.26 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
