1-(4-Bromophenyl)-3-(2,4-dichloro-5-fluorophenyl)-1H-pyrazole-4-carbaldehyde CAS 618101-59-0

Description

The molecular framework of 1-(4-Bromophenyl)-3-(2,4-dichloro-5-fluorophenyl)-1H-pyrazole-4-carbaldehyde (C16H8BrCl2FN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 1-(4-Bromophenyl)-3-(2,4-dichloro-5-fluorophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618101-59-0), a certified reference material (molecular formula C16H8BrCl2FN2O, MW 414.06 g/mol) for analytical method development and quality control.

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.
