3,3',4,4',5,5'-Hexabromodiphenyl ether CAS 446255-18-1

Description

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.

3,3',4,4',5,5'-Hexabromodiphenyl ether (CAS 446255-18-1), molecular formula C12H4Br6O and molecular weight 643.58 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H4Br6O, 3,3',4,4',5,5'-Hexabromodiphenyl ether contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 643.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3,3',4,4',5,5'-Hexabromodiphenyl 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.
