Chemical Structure
Description
2,2'-(((9H-fluorene-9,9-diyl)bis(naphthalene-6,2-diyl))bis(oxy))bis(ethan-1-ol) (C37H30O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
