5-triazine-6-yl)amino-4'-nitrostilbene-2,2'-disulfonateby using Tin(II) chloride as the reducing agent. Using this intermediate, nineteen new asymmetrically substitutedbistriazinylstilbene fluorescent brightening agents were synthesized. Chemical structures of the obtainedcompounds 5a-s were analyzed by proton NMR spectrum. The physical properties of the new compounds5a-s were characterized by fastness test
