2,3,3',5,5'-Pentabromodiphenyl ether CAS 446254-74-6

Description

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

CATO supplies 2,3,3',5,5'-Pentabromodiphenyl ether (CAS 446254-74-6), a certified reference material (molecular formula C12H5Br5O, MW 564.69 g/mol) for analytical method development and quality control.

Structurally, 2,3,3',5,5'-Pentabromodiphenyl ether (C12H5Br5O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 564.69 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
