Disopyramide immunogens, antibodies prepared therefrom, labeled conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immunoassays for determining disopyramide. The immunogens comprise disopyramide coupled by an ether linkage at a selected singular position on its phenyl ring to an immunogenic carrier material. Likewise, the labeled conjugates and synthetic intermediates are phenyl ether derivatives of disopyramide or precursors thereof. The antibody and labeled conjugates are particularly useful in homogeneous nonradioisotopic immunoassays for measuring disopyramide in biological fluids such as serum.
