Description

Compared with other compounds in its class, the molecular weight of 228.63 g/mol gives 4-Chloro-3-(difluoromethyl)-5-phenyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-3-(difluoromethyl)-5-phenyl-1H-pyrazole (CAS 1029636-02-9) is a high-purity analytical reference standard with the molecular formula C10H7ClF2N2 and a molecular weight of 228.63 g/mol.

4-Chloro-3-(difluoromethyl)-5-phenyl-1H-pyrazole (C10H7ClF2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
