Disclosed herein are derivatives of 5-(lower alkyl)-7-amino-2,3-dihydro-1,4-phthalazinedione having substituents on the amino group. The derivatives have luminescent properties which render them useful as analytical tools in clinical chemistry. Adaptation of the derivatives for luminescent immunoassay provides valuable reagents and assays with outstanding sensitivity.
we have prepared some new isoluminol, 7-(N,N-dialkylamino)-5-methyl-2,3-dihydrophthalazine-1,4-diones by means of a novel procedure involving the cycloaddition of dienamines to maleic acid derivatives. These compounds are characterized by the presence of a methyl group at C-5 and give quantum yields three to five times greater than those of the most efficient isoluminols in use at present.
