Chemically, benzoylecgonine is the benzoate ester of ecgonine. It is a primary metabolite of cocaine, and is pharmacologically inactive. Urinalysis. Benzoylecgonine is the compound tested for in most substantive cocaine drug urinalyses. It is the corresponding carboxylic acid of cocaine, its methyl ester.

Ecgonine is suggested to be a promising marker of cocaine (COC) ingestion. A combined mass spectrometry (MS) and tandem MS (MS/MS) method was developed to simultaneously determine ecgonine and seven other metabolites of cocaine in human urine and whole blood with ultra-high-pressure liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.
