Amino-functionalized phthalhydrazide intermediates of the formula: ##STR1## wherein one of R.sup.5 and R.sup.6 is hydrogen and the other is --NR.sup.7 R.sup.8 ; R.sup.7 is hydrogen or straight chain alkyl containing 1-4 carbon atoms and R.sup.8 is ##STR2## wherein n=1-3. The compounds are intermediates in the synthesis of chemiluminescent-labeled conjugates which are useful as reagents in specific binding assays for determining ligands or their specific binding partners in liquid media.
公式:##STR1##其中R.sup.5和R.sup.6中的一个是氢,另一个是--NR.sup.7 R.sup.8; R.sup.7是氢或含有1-4个碳原子的直链烷基,R.sup.8是##STR2##其中n=1-3。这些化合物是合成
