Abstract: In order to obtain a new solid phase time-resolved fluorescence immunoassay chelate, a new intermediate compound 4,4'-(p-aminophenylethynyl)-6,6'-bis[N,N-bis(ethoxycarbonylmethyl)amino methyl]-2,2'-bipyridine was prepared from 4,4'-dinitro-2,2'-bipyridine-6,6'-dimethyl bis(trifluoroacetate) by hydrolyzation, bromination, esterification and substitution. The structure of the compound was charactered by DSC, IR, 1H NMR and HRMS. The compound was hydrolyzed in the solution of europium ion, forming a rare earth fluorescence chelate. The fluorescence spectrum of the chelate excited by an light source has peaks peculiar to the europium ion.

Key words: Solid phase time-resolved fluorescence immunoassay, Chelant, Intermediate, 4,4'-Di(p-aminophenylethynyl)-6,6'-bis[N,N-bis(ethoxycarbonylmethyl)amino methyl]-2,2'-bipyridine
