Novel chemical analogs of the methadone metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) are disclosed. The derivatives can be used for formation of EDDP-protein conjugates. The conjugates can be used in turn to raise antibodies reactive with EDDP and having a low cross-reactivity with methadone. The antibodies and EDDP-enzyme polypeptide conjugates provide the basis for specific immunoassays used in monitoring compliance with methadone treatment.
