Abstract
Nitrogen derivatives of benzoyl ecgonine and cocaine are provided, particularly amino, diazonium, and diazo derivatives, the compounds finding use either directly or as intermediates for the preparation of reagents for use in immunoassays. Diazo compounds can be coupled with antigenic materials for the preparation of antibodies to benzoyl ecgonine and/or cocaine. The amino group can be combined with active non-oxo-carbonyl compounds to form reagents which find use in immunoassays.
