Isatoic anhydride derivatives having an N-substituent which includes a quaternary ammonium group are useful for labeling and/or functionalizing a target material and/or for coupling materials together. The isatoic anhydride derivatives of the present disclosure can be advantageously water soluble, easily prepared and purified. Isatoic anhydride derivatives useful in the present disclosure preferably have at least one chemically reactive group or at least one binding group or at least one detectable label. Anthranilate derivatives made from the isatoic anhydrides derivatives or otherwise and kits including the isatoic anhydride derivatives are also disclosed.

observed: these results can be interpreted within the ‘dimer nucleophile’ mechanism where the amine homo-aggregates are better nucleophiles than the amine monomers. To confirm this interpretation, the reaction of 2,4-dinitrofluorobenzene with histamine was studied in the same solvent. Because of the rigid geometry, an intramolecular hydrogen bond is easily established, which prevents the formation of self-aggregates

although other alternative mechanisms were suggested to explain the fourth‐order kinetics, no one has been able to explain the other above‐mentioned features. The present paper affords additional experimental evidence and derivation of the kinetic expressions for reactions with good nucleofugues, where the first step is rate determining. The work involves studies of the reactions of 2,4‐dinitrofluorobenzene
