Chemical Structure
Description
The occurrence of 7-Fluoro-6-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid 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.
7-Fluoro-6-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (CAS 622369-36-2) is a high-purity analytical reference standard with the molecular formula C11H8FNO4 and a molecular weight of 237.18 g/mol.
7-Fluoro-6-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (C11H8FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), 7-Fluoro-6-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
