Abstract
Intermediates in the preparation of 9-position derivatives of theophylline useful in synthesizing theophylline immunogens and labeled conjugates. The labeled conjugates and the antibodies produced against the immunogens are particularly useful in homogeneous nonradioisotopic immunoassay for measuring theophylline in biological fluids such as serum.
