Chemical Structure
Description
(11bS)-2,6-Bis(3,5-dichlorophenyl)-4-hydroxydinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (C32H17Cl4O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
