Chemical Structure
Description
The molecular framework of 3,4-Dibromo-6-ethoxy-2-(hydroxymethyl)phenol (C9H10Br2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
3,4-Dibromo-6-ethoxy-2-(hydroxymethyl)phenol (CAS 35090-69-8), molecular formula C9H10Br2O3 and molecular weight 325.98 g/mol, is a CATO reference standard with documented purity and traceability.
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.
