Chemical Structure

2,2＇,3,3＇,4,4＇,5,5＇-Octabromobiphenyl CAS 67889-00-3 chemical structure

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.

CATO supplies 2,2＇,3,3＇,4,4＇,5,5＇-Octabromobiphenyl (CAS 67889-00-3), a certified reference material (molecular formula C12H2Br8, MW 785.38 g/mol) for analytical method development and quality control.

Structurally, 2,2＇,3,3＇,4,4＇,5,5＇-Octabromobiphenyl (C12H2Br8) contains 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 785.38 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
