title: Evidence of nucleophilic addition to chemiluminescent N-sulfonylacridinium-9-carboxamides from electrospray ionization mass spectrometry.
abstract: Addition of nucleophiles to the chemiluminescent acridinium-9-carboxamide 1 resulted in the formation of the acridan adduct 7. The relative ratio of 1/7 present in solution could be determined by electrospray ionization mass spectrometry (ESI-MS) for a number of nucleophiles that are commonly employed during the use of 1 as a label in medical diagnostic assays.
