[Synthesis and characterization of a time-resolved fluorescence analysis chelate reagent-BCPDA].
In this paper, we report on a solid phase time-resolved fluorescence immunoassay chelate reagent-4,7-bis(chlorosulfophenyl)-1,10-phenanthroline-2,9-dicarboxylic acid (BCPDA), which is suitable as a fluorescent labeling agent. The five step synthesis product of BCPDA was presented for improving the purity of the product based on the three step synthesis product. The approach involves chlorization, hydrolyzing the ester, preparing disodium, carboxylate to diacid, sulfonation. The yield of five step product is 99%, 45%, 94%, 95%, 80% respectively. The structure and purity of product was characterized by the melting point, IR, 1H NMR, UV spectrum, element analysis, and proved to be consistent with the structure predictal.
