Chemical Structure
Description
The molecular framework of 1,6-Dibromo-2-ethoxynaphthalene (C12H10Br2O) 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).
1,6-Dibromo-2-ethoxynaphthalene (CAS 891194-44-8) is a high-purity analytical reference standard with the molecular formula C12H10Br2O and a molecular weight of 330.02 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.
