1-(2,4-Difluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde CAS 618101-83-0

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(2,4-Difluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

1-(2,4-Difluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618101-83-0) is a high-purity analytical reference standard with the molecular formula C16H9F2N3O3 and a molecular weight of 329.26 g/mol.

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.
