56394-22-0 6-bromanyl-4-methyl-2-oxidanylidene-chromene-3-carbonitrile 6-bromo-4-methyl-2-oxo-1-benzopyran-3-carbonitrile A831031 (CAS 56394-22-0) is a high-purity analytical reference standard with the molecular formula C11H12BrNO2 and a molecular weight of 270.12 g/mol.
56394-22-0 6-bromanyl-4-methyl-2-oxidanylidene-chromene-3-carbonitrile 6-bromo-4-methyl-2-oxo-1-benzopyran-3-carbonitrile A831031 (C11H12BrNO2) 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.
