An investigation of naphthalene-2,3-dicarboxaldehyde (NDA) as a potential derivatising reagent for the fluorimetric determination of amines and amino acids in the presence of beta-cyclodextrin has been conducted. Enhanced fluorescence was observed in most cases. Experimental conditions, including pH of the medium, are optimised for the formation of the fluorescent NDA-derivatives. The fluorimetric determination of amines and amino acids by the beta-cyclodextrin - enhanced fluorimetry is reported along with an expected possible mechanism of these beta-cyclodextrin - included reactions.
