Fluorescence ability was examined With the reaction mixture of 2,3-naphthalene-dicarboxaldehyde and aromatic primary amines. In a strongly acid medium. the solution was found to exhibit fluorescence reaction different from that of previously reported o-phthalaldehyde or 4,5-methylenedioxyphthalaldehyde. By the utilizgtion of this fluorescence reaction fluorometric determination of aromatic primary amines with 2,3-naph-thalenedicarboxaldehyde was established. Sensitivity of this method is approximately equal to that using 4,5-methylenedioxyphthalaldehyde. It was found from fluorescence characteristics of 2-(p-sulfamoylphenyl)-benz[f]isoindoline-1,3-diol and of the reaction mixture that this fluorescent substance is 2-phenylbenz[f]isoindoline-1,3-diol, and it Was assumed that the fluorescence in a strongly acid medium is due to ite halochromism.
