Abstract

Abstract Novel urea derivatives of oxazine and thiazine chromophors have the structural formula I or II. ##STR1## wherein M is oxygen or sulfur, R 1 and R 2 are aliphatic alkyl groups or hydrogen; R 3 is hydrogen or alkyl group; R 4 is hydrogen, alkyl or amine group; R 5 is hydrogen, amine or alkyl group; X.sup.⊖ is an anion consisting of an organic (e.g. CH 3 COO.sup.⊖, CH 3 CH 2 COO.sup.⊖ and the like) or inorganic specie (e.g. Cl.sup.⊖, Br.sup.⊖, I.sup.⊖, ClO 4 .sup.⊖, SO 4 ", and the like); n is 0 to 20; Z is N═C═O, N═C═S, carboxylic, primary or secondary amine, and when n=0, Z may be ##STR2## wherein Q is hydroxyl, amino, carboxylic, sulfydryl, isocyanato, or isothiocyanato. The functional oxazine-urea and thiazine-urea derivatives react with compounds of interest to form adducts resulting in the fluorescent labeling of the compound.
