Despropionyl meta-fluorofentanyl (Item No. 20125) is an analytical reference material that is structurally similar to known opioids. Despropionyl meta-fluorofentanyl is a precursor to meta-fluorofentanyl and meta-fluorobutyryl fentanyl and a potential impurity in illicit preparations of this class of compounds. It is also a potential metabolite of meta-fluorofentanyl and meta-fluorobutyryl fentanyl based on the published metabolism of fentanyl. At the time despropionyl meta-fluorofentanyl (Item No. 20125) was made available for purchase, specific metabolism data had not been published.
