Description
The occurrence of (11bR)-2,6-Dibromo-4-hydroxy-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide is closely related to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(11bR)-2,6-Dibromo-4-hydroxy-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (CAS 1065214-93-8), molecular formula C20H19Br2O4P and molecular weight 514.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution, (11bR)-2,6-Dibromo-4-hydroxy-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 514.14 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.
