Chemical Structure

2,2',3,3',4,4',5,5'-Octabromodiphenyl ether CAS 85446-17-9 chemical structure

Description

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.

2,2',3,3',4,4',5,5'-Octabromodiphenyl ether (CAS 85446-17-9), molecular formula C12H2Br8O and molecular weight 801.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2,2',3,3',4,4',5,5'-Octabromodiphenyl ether is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 801.38 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.

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