Chemical Structure

2,2',4,5,5'-Pentabromobiphenyl CAS 67888-96-4 chemical structure

Description

Owing to bromine substitution, an aromatic ring system, 2,2',4,5,5'-Pentabromobiphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 548.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2,2',4,5,5'-Pentabromobiphenyl (CAS 67888-96-4), molecular formula C12H5Br5 and molecular weight 548.69 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
