Persistent Urinary Benzoylecgonine Following Cocaine Use

The American Journal on Addictions, 1992
The authors examine the utility of a fluorescence polarization immunoassay (the ADx Cocaine Metabolite Assay) for the determination of benzoylecgonine in 41 patients (28 women and 13 men) admitted to an inpatient substance abuse treatment unit following recent cocaine use. The assay remained positive (i.e., exceeded 300 ng/ml) in urine for a mean of 84.

Preparation of deuterium-labeled cocaine and benzoylecgonine.

Research communications in chemical pathology and pharmacology, 1975
The preparation of deuterium-labeled cocaine and benzoylecgonine by a site-specific method is reported. This method involves the reductive dehalogenation of appropriately substituted derivatives by a NaBD4 - PdCl2 system. By the judicious choice of halogen-substituted aromatic systems, a wide variety of specifically deuterated compounds of biological ...
