Chemical Structure
Description
6-Iodo-5-methylnicotinic acid (C7H6INO2) contains an amide group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
