3-(2,4-Dichloro-5-fluorophenyl)-1-(2-fluorophenyl)-1H-pyrazole-4-carbaldehyde CAS 618101-82-9

Description

The occurrence of 3-(2,4-Dichloro-5-fluorophenyl)-1-(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.

3-(2,4-Dichloro-5-fluorophenyl)-1-(2-fluorophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618101-82-9) is a high-purity analytical reference standard with the molecular formula C16H8Cl2F2N2O and a molecular weight of 353.15 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-(2,4-Dichloro-5-fluorophenyl)-1-(2-fluorophenyl)-1H-pyrazole-4-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.15 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
