Chemical Structure
Description
The occurrence of 7-fluoro-1,4-dihydro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-6-iodo-4-oxo-3-Quinolinecarboxylic acid ethyl ester is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-fluoro-1,4-dihydro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-6-iodo-4-oxo-3-Quinolinecarboxylic acid ethyl ester (CAS 697762-60-0), molecular formula C17H19FINO4 and molecular weight 447.24 g/mol, is a CATO reference standard with documented purity and traceability.
7-fluoro-1,4-dihydro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-6-iodo-4-oxo-3-Quinolinecarboxylic acid ethyl ester (C17H19FINO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 7-fluoro-1,4-dihydro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-6-iodo-4-oxo-3-Quinolinecarboxylic acid ethyl ester 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.
