Metabolism and pharmacology

Pentylone is a known metabolite of Dimethylpentylone.

Society and Culture

Dimethylpentylone was first detected in toxicology samples in the United States towards the end of 2021. The Center for Forensic Science Research and Education (CFSRE) has closely monitored its presence through the NPS Discovery program. It has been observed that Dimethylpentylone is increasingly being mislabeled and sold as MDMA, similar to the trend previously seen with Eutylone being misrepresented as MDMA.

On June 26, 2023, the United States Customs and Border Protection intercepted a shipment of 32.2 kilograms of Dimethylpentylone. This shipment, originating from China and falsely labeled as “beauty products,” was destined for an address in Washington, D.C.

Furthermore, on July 10, 2023, an interview with Jacksonville DEA Assistant Special Agent in Charge Mike Dubet revealed that Dimethylpentylone has been discovered in the possession of individuals frequenting nightclubs and bars in the Jacksonville, Florida area.


In the United States, Dimethylpentylone is not explicitly designated under the Controlled Substances Act. However, it would be categorized as a Schedule I substance due to its status as a positional isomer of N-Ethylpentylone, which is a Schedule I substance in the United States. The definition of “all isomers” within that context encompasses Dimethylpentylone within this classification.
