The 6-hydroxyindole metabolite of AM2201 is primarily studied in the context of forensic and toxicological research. It serves as a key biomarker for detecting the use of AM2201, a synthetic cannabinoid, in biological samples such as urine, blood, or hair. This metabolite is crucial for identifying and confirming exposure to AM2201, especially in cases of drug abuse or overdose. Its presence helps law enforcement and healthcare professionals assess drug use patterns and provide appropriate interventions. Additionally, research on this metabolite contributes to understanding the metabolic pathways and potential health effects of synthetic cannabinoids.
