2,3,3',4,6-Pentabromodiphenyl Ether CAS 446254-72-4

Description

Compared with other compounds in its class, the molecular weight of 564.69 g/mol gives 2,3,3',4,6-Pentabromodiphenyl Ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,3',4,6-Pentabromodiphenyl Ether (CAS 446254-72-4), molecular formula C12H5Br5O and molecular weight 564.69 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,3,3',4,6-Pentabromodiphenyl Ether (C12H5Br5O) 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).

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), 2,3,3',4,6-Pentabromodiphenyl Ether 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.
