5-fluoro ADB-PINACA is primarily used in research settings to study its effects on cannabinoid receptors, particularly CB1 and CB2. It is often investigated for its potential psychoactive properties and its impact on the endocannabinoid system. Researchers analyze its binding affinity and functional activity to better understand synthetic cannabinoids and their interactions with the human body. This compound is also of interest in forensic science, where it is identified and studied in cases involving synthetic cannabinoid abuse or intoxication. Additionally, it serves as a reference material in the development of analytical methods for detecting synthetic cannabinoids in various samples.
