Benzoylecgonine D5

Benzoylecgonine D5 is a stable isotope labeled analog of benzoylecgonine, a metabolite of cocaine. It is commonly used in forensic toxicology to detect cocaine use in drug tests. Benzoylecgonine D5 is a synthetic compound that contains five heavy hydrogen atoms, which allows it to be distinguished from the naturally occurring compound and accurately quantified in biological samples. The chemical formula of Benzoylecgonine D5 is C16H17D5NO4, and its molecular weight is 301.4 g/mol. It is a white crystalline powder that is soluble in water and organic solvents such as methanol and acetonitrile. In drug testing, Benzoylecgonine D5 is added to urine or blood samples as an internal standard. The internal standard helps to control for variations in sample preparation, extraction, and analysis, ensuring accurate and reliable results. Benzoylecgonine D5 is also used as a reference material for calibration of analytical instruments. While Benzoylecgonine D5 is not used for any medical or therapeutic purposes, it plays a critical role in forensic toxicology and drug testing. Its precise chemical structure and isotopic labeling make it a valuable tool for detecting and quantifying cocaine use in biological samples, helping to ensure public safety and prevent drug abuse.
