3-(4-Bromophenyl)-1-(4-methoxyphenyl)-1H-pyrazole-4-carbaldehyde CAS 618098-61-6

Description

Based on its molecular formula C17H13BrN2O2, 3-(4-Bromophenyl)-1-(4-methoxyphenyl)-1H-pyrazole-4-carbaldehyde contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 357.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 3-(4-Bromophenyl)-1-(4-methoxyphenyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-61-6), a certified reference material (molecular formula C17H13BrN2O2, MW 357.20 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.
