Chemical Structure
Description
1,2,3,4,6,7,8-Heptabromodibenzo-p-dioxin (CAS 110999-47-8), molecular formula C12HBr7O2 and molecular weight 736.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1,2,3,4,6,7,8-Heptabromodibenzo-p-dioxin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 736.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
