Chemical Structure
Description
7-Bromo-2-methylquinoline-4-carboxylic acid (C11H8BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
7-Bromo-2-methylquinoline-4-carboxylic acid (CAS 923715-61-1) is a high-purity analytical reference standard with the molecular formula C11H8BrNO2 and a molecular weight of 266.09 g/mol.
