Abstract
Carbonyl derivatives of acetaminophen are provided for use in homogeneous enzyme immunoassays for acetaminophen. The derivatives are conjugated to antigenic substances for the preparation of antisera specific to acetaminophen, and to enzymes for the preparation of enzyme conjugates which compete with acetaminophen for antibody binding sites in a typical assay.
