The AM2201 N-(4-hydroxypentyl) metabolite is primarily studied in the context of forensic and toxicological research. It is a major metabolite of the synthetic cannabinoid AM2201, which is often detected in biological samples such as blood, urine, or hair. Its identification is crucial for confirming the use of AM2201 in cases of drug abuse or intoxication. In forensic laboratories, this metabolite serves as a biomarker to differentiate AM2201 consumption from other substances, aiding in legal and medical investigations. Additionally, it is used in research to understand the metabolic pathways and pharmacokinetics of synthetic cannabinoids, contributing to the development of detection methods and harm reduction strategies.
