The Uses of DANSYLAMIDE
5-(Dimethylamino)-1-naphthalenesulfonamide (DNSA) was used as starting reagent in the synthesis of 2,6-disubstituted pyridines, 6-substituted 2,2′-bipyridines and 6,6′-disubstituted 2,2′-bipyridines. It was also used as fluorescent probe in the determination of concentration of human carbonic anhydrase II-DNSA in solutions.
