Chemical Structure
Description
Bisphenol A Bis(diphenyl phosphate) (C39H34O8P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
