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.
2,4,6,8-Tetrabromodibenzo[b,d]furan (CAS 617707-91-2) is a high-purity analytical reference standard with the molecular formula C12H4Br4O and a molecular weight of 483.78 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2,4,6,8-Tetrabromodibenzo[b,d]furan is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 483.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
