Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4,4',6-Tetrabromodiphenyl Ether (CAS 189084-63-7) is a high-purity analytical reference standard with the molecular formula C12H6Br4O and a molecular weight of 485.79 g/mol.
Based on its molecular formula C12H6Br4O, 2,4,4',6-Tetrabromodiphenyl 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 485.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
