Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-3,4-dichlorobenzophenone 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.
CATO supplies 4-Bromo-3,4-dichlorobenzophenone (CAS 844879-06-7), a certified reference material (molecular formula C13H7BrCl2O, MW 330.00 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-3,4-dichlorobenzophenone (C13H7BrCl2O) 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 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).
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.
