Diethyl 1-(4-fluorophenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate CAS 96722-82-6

Description

Diethyl 1-(4-fluorophenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate (CAS 96722-82-6) is a high-purity analytical reference standard with the molecular formula C21H19FN2O4 and a molecular weight of 382.38 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Diethyl 1-(4-fluorophenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
