2,3,4',5-Tetrabromodiphenyl ether CAS 446254-34-8

Description

The occurrence of 2,3,4',5-Tetrabromodiphenyl ether is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3,4',5-Tetrabromodiphenyl ether (CAS 446254-34-8), a certified reference material (molecular formula C12H6Br4O, MW 485.79 g/mol) for analytical method development and quality control.

2,3,4',5-Tetrabromodiphenyl ether (C12H6Br4O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,3,4',5-Tetrabromodiphenyl 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.
