5F-AB-FUPPYCA, or AZ-037, is a synthetic cannabinoid rooted in the pyrazole structure. It is presumed to act as an agonist targeting the CB1 receptor and has gained popularity as a designer drug available for purchase online. Notably, it came into the spotlight when the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) identified it in a seizure of 540 grams of white powder in France in February 2015.
Interestingly, AZ-037 is also a synonym for another compound, 5-fluoro-3,5-AB-PFUPPYCA, which shares a structural isomer with AZ-037. This results in AZ-037 being used interchangeably for these two different substances.
Notably, 5-fluoro-3,5-AB-PFUPPYCA made its appearance in synthetic cannabinoid smoke blends in the United States as early as December 30, 2021, alongside substances like ADB-BUTINACA, MDA-19 (BZO-HEXOXIZID), and MDMB-4en-PINACA.
With structural elements reminiscent of other synthetic cannabinoids, such as AB-CHFUPYCA, JWH-307, JWH-030, JWH-147, and AB-PINACA, 5-fluoro-AB-PFUPPYCA can be considered an analog of the traditional pyrazole cannabinoid receptor one antagonist, rimonabant. However, it’s important to note that the pharmacological properties of 5F-AB-FUPPYCA still need to be explored and unstudied.

In the United States, as of May 22, 2023, 5F-AB-FUPPYCA remains unscheduled at the federal level. It could fall under the purview of the federal analog act, either due to its pharmacological properties or as a remote structural analog of JWH-307.
However, in North Dakota, a different stance has been taken. On April 27, 2023, North Dakota categorized 5F-AB-FUPPYCA (N-(1-carbamoyl-2-methyl-propyl)-2-(5-fluoropentyl)-5-(4-fluorophenyl)pyrazole-3-carboxamide) as a Schedule I substance. It’s worth noting that this classification does not extend to structural substitutions or other analogs within the pyrazole category, excluding non-fluorinated AB-FUPPYCA analogs, for instance.
