Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.27 g/mol gives Diethyl 7-fluoroquinoline-2,3-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Diethyl 7-fluoroquinoline-2,3-dicarboxylate (CAS 948290-82-2), a certified reference material (molecular formula C15H14FNO4, MW 291.27 g/mol) for analytical method development and quality control.
Diethyl 7-fluoroquinoline-2,3-dicarboxylate (C15H14FNO4) 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.
As a certified reference material (CRM), Diethyl 7-fluoroquinoline-2,3-dicarboxylate 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.
