Chemical Structure
Description
The molecular framework of 1-Bromo-5-(4-ethoxybenzyl)-2-methoxy-4-methylbenzene, 97% (C17H19BrO2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1-Bromo-5-(4-ethoxybenzyl)-2-methoxy-4-methylbenzene, 97% (CAS 898538-39-1) is a high-purity analytical reference standard with the molecular formula C17H19BrO2 and a molecular weight of 335.24 g/mol.
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.
