Chemical Structure
Description
5-Iodo-2,3-dimethoxybenzaldehyde (C9H9IO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Iodo-2,3-dimethoxybenzaldehyde (CAS 7396-66-9), molecular formula C9H9IO3 and molecular weight 292.07 g/mol, is a CATO reference standard with documented purity and traceability.
