Chemical Structure
Description
7-Iodo-9H-fluorene-4-carboxylic acid (C14H9IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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).
7-Iodo-9H-fluorene-4-carboxylic acid (CAS 16218-33-0) is a high-purity analytical reference standard with the molecular formula C14H9IO2 and a molecular weight of 336.12 g/mol.
