Chemical Structure
Description
2,6-Dichloro-4-methoxybenzyl bromide (CAS 94278-70-3), molecular formula C8H7BrCl2O and molecular weight 269.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichloro-4-methoxybenzyl bromide (C8H7BrCl2O) is characterized by a hydroxyl group, an ether linkage, chlorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2,6-Dichloro-4-methoxybenzyl bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
