Chemical Structure
Description
2,4,6-Triiodobenzoic acid (C7H3I3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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).
2,4,6-Triiodobenzoic acid (CAS 2012-31-9) is a high-purity analytical reference standard with the molecular formula C7H3I3O2 and a molecular weight of 499.81 g/mol.
