Benzoylecgonine is the main metabolite of cocaine, formed by the liver and excreted in the urine. It is the compound tested for in most cocaine urine drug screens and in wastewater screenings for cocaine use.
==Biochemistry and physiology== Chemically, benzoylecgonine is the benzoate ester of ecgonine. It is a primary metabolite of cocaine, and is pharmacologically inactive. It is the corresponding carboxylic acid of cocaine, its methyl ester. It is formed in the liver by the metabolism of cocaine by hydrolysis, catalysed by carboxylesterases, and subsequently excreted in the urine. It is readily synthesised by boiling cocaine freebase in water.
