DOWNLOAD THE DATABASE4-ANPP-d5 (exempt preparation) (Item No. 36781) is intended for use as an internal standard for the quantification of 4-ANPP (Item Nos. 22700 | 18810) by GC- or LC-MS. 4-ANPP is categorized as an opioid metabolite and a precursor in the synthesis of fentanyl (Item Nos. ISO60197 | 22659 | 14719) and other opioids.1,2,3,4,5 4-ANPP is a metabolite of acetyl fentanyl (Item Nos. ISO60128 | ISO00128), butyryl fentanyl (Item Nos. 19734 | 14728), furanyl fentanyl (Item Nos. 19633 | 18705), acrylfentanyl (Item Nos. 23060 | 19312), and fentanyl.1,2,3,4 It has also been found as an impurity in illicit fentanyl preparations.6 4-ANPP-d5 is regulated as a Schedule II compound in the United States. 4-ANPP-d5 (exempt preparation) (Item No. 36781) is provided as a DEA exempt preparation. This product is intended for research and forensic applications.
