2,2',3,5,5'-Pentabromodiphenyl ether CAS 446254-59-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2',3,5,5'-Pentabromodiphenyl ether.

CATO supplies 2,2',3,5,5'-Pentabromodiphenyl ether (CAS 446254-59-7), a certified reference material (molecular formula C12H5Br5O, MW 564.69 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H5Br5O, 2,2',3,5,5'-Pentabromodiphenyl 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 564.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures 2,2',3,5,5'-Pentabromodiphenyl ether under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
