Acridinium sulfonylamides and isomers, such as phenanthridinium sulfonylamides, may be employed in applications including chemiluminmescent immunoassays. Methods for synthesis of these compounds include contacting an amine with a sulfonylhalide to form a sulfonamide and acylating with an activated carboxylic acid of an acridine or isomer thereof. The N-sulfonyl-9-acridinium carboxamide and isomers may be conjugated to antigens, haptens, antibodies, and nucleic acids for use in chemiluminescent assays.
