The detection of benzoylecognine is carried out by means of surface plasmon resonance.

Two alternative methods are provided for analyzing the SPR data collected to determine the concentration of benzoylecognine.

In January 2015, Jones tested positive for benzoylecgonine, a cocaine metabolite.

Cocaine is excreted in the urine primarily as benzoylecgonine in a short period.

The ethyl ester of derivatives of benzoyl ecgonine are provided having a linking group at the para position of the benzoyl group.

Cocaine is excreted in urine primarily as benzoylecgonine in a short period of time.

No limit is recommended for benzoylecgonine, the inactive breakdown product of cocaine.

A mother’s hair test showed high levels of cocaine and benzoylecgonine (its metabolite).

It is structurally similar to cocaine, which is the methyl ester of benzoylecgonine.

The main metabolites are benzoylecgonine, ecgonine and ecgonine methyl ester, all of which are inactive.

He tested positive for benzoylecgonine, the main metabolite in cocaine.

The invention is characterized in that it provides a novel immunosensor surface that enables direct real time detection of benzoylecognine, the main metabolite of cocaine.

When someone consumes cocaine, the body produces two chemical compounds: benzoylecgonine and methylecgonine.

Urea and most urea derivatives allow converting cocaine into benzoylecgonine, during the step of contacting, which increases the sensitivity to cocaine of the quick test.

The drugs involved included marijuana, alcohol (ethanol), benzoylecgonine (a cocaine-related substance), benzodiazepines (medications used for sedation or to treat anxiety), and morphine.
