4-AMINOPHENYL-1-PHENETHYLPIPERIDINE Usage And Synthesis

Description

4-ANPP (Item No. 18810) is an analytical reference material categorized as an opioid metabolite and a precursor in the synthesis of fentanyl (Item Nos. ISO60197 | 22659 | 14719) and other opioids. 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. It has also been found as an impurity in illicit fentanyl preparations. 4-ANPP is regulated as a Schedule II compound in the United States. This product is intended for research and forensic applications.

Description

4-ANPP (CRM) (Item No. 22700) is a certified reference material that is categorized as a piperidinamine. It is an intermediate in the synthesis of fentanyl (Item Nos. 22659 | 14719 | ISO60197) from N-phenethyl-4-piperidone (NPP; ). As such, 4-ANPP has been used as a precursor for the manufacture of fentanyl and related opioids. 4-ANPP is also an impurity found in fentanyl preparations. It is a known metabolite of acetyl fentanyl (Item Nos. ISO00128 | ISO60128), butyryl fentanyl (Item Nos. 14728 | 19734), furanyl fentanyl (Item Nos. 18705 | 19633), acrylfentanyl , and fentanyl. 4-ANPP is regulated as a Schedule II compound in the United States. This product is intended for research and forensic applications.
