Chemical Structure
Description
The molecular framework of 2-Bromo-7-methyl-3,4-dihydronaphthalen-1(2H)-one (C11H11BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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).
2-Bromo-7-methyl-3,4-dihydronaphthalen-1(2H)-one (CAS 104115-64-2) is a high-purity analytical reference standard with the molecular formula C11H11BrO and a molecular weight of 239.11 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.
