Fluorescence properties of glafenine.

The fluorescence properties of glafenine are partly caused by the anthranilic acid nucleus of the molecule. Correlations are made between fluorescence capacities and UV absorbance. Analytical determinations can be carried out in different solvents, e.g., ether, benzene, and ethanol. Linearity of the emission intensity with the concentration, limiting detectable sample concentrations, and Stokes shifts are reported.
