Chemical Structure
Description
The occurrence of (R)-6,7,8-Trifluoro-1,4-dihydro-1-(2-hydroxy-1-methylethyl)-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (R)-6,7,8-Trifluoro-1,4-dihydro-1-(2-hydroxy-1-methylethyl)-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester (CAS 110548-05-5), a certified reference material (molecular formula C15H14F3NO4, MW 329.27 g/mol) for analytical method development and quality control.
(R)-6,7,8-Trifluoro-1,4-dihydro-1-(2-hydroxy-1-methylethyl)-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester (C15H14F3NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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 (R)-6,7,8-Trifluoro-1,4-dihydro-1-(2-hydroxy-1-methylethyl)-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.
