Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 453.32 g/mol gives (3-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-1H-pyrazol-1-yl)(4-methoxyphenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-1H-pyrazol-1-yl)(4-methoxyphenyl)methanone (CAS 477712-62-2), a certified reference material (molecular formula C24H18Cl2N2O3, MW 453.32 g/mol) for analytical method development and quality control.
The molecular framework of (3-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-1H-pyrazol-1-yl)(4-methoxyphenyl)methanone (C24H18Cl2N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
