Chemical Structure
Description
Based on its molecular formula C14H13ClN2O5C2H6O, Ethyl 7-chloro-1-ethyl-6-nitro-4-oxo-1,4-dihydro-3-quinolinecarboxylate : ethanol (1:1) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 370.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ethyl 7-chloro-1-ethyl-6-nitro-4-oxo-1,4-dihydro-3-quinolinecarboxylate : ethanol (1:1) (CAS 2098500-77-5) is a high-purity analytical reference standard with the molecular formula C14H13ClN2O5C2H6O and a molecular weight of 370.79 g/mol.
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.
