Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 377.27 g/mol gives 4-Bromo-2-(2-(4-(tert-butyl)phenoxy)ethoxy)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2-(2-(4-(tert-butyl)phenoxy)ethoxy)benzaldehyde (CAS 1432437-10-9), a certified reference material (molecular formula C19H21BrO3, MW 377.27 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2-(2-(4-(tert-butyl)phenoxy)ethoxy)benzaldehyde (C19H21BrO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, 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. 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.
