INTERMEDIATES USEFUL IN THE SYNTHESIS OF CHEMILUMINESCENT PHTHALHYDRAZIDELABELLED CONJUGATES

摘要

Chemiluminescent-labeled conjugates of the formula: wherein one of R1 and R2 is hydrogen and the other is -NR3R4; R3 is hydrogen or straight chain alkyl containing 1-4 carbon atoms and R4 is L(CO-HN-CH2)n wherein n=2-8 and L(CO)- is a hapten bound through an amide bond. The labeled conjugates are useful as reagents in specific binding assays for determining haptens or their specific binding partners in liquid media.
