1-(4-Chloro-2-fluorophenyl)-1H-pyrazole-4-carbaldehyde CAS 2379321-65-8 chemical structure

Description

The occurrence of 1-(4-Chloro-2-fluorophenyl)-1H-pyrazole-4-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Chloro-2-fluorophenyl)-1H-pyrazole-4-carbaldehyde (CAS 2379321-65-8) is a high-purity analytical reference standard with the molecular formula C10H6ClFN2O and a molecular weight of 224.62 g/mol.

1-(4-Chloro-2-fluorophenyl)-1H-pyrazole-4-carbaldehyde (C10H6ClFN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
