2 Bromoethyl Benzene CAS#103-63-9
2 Bromoethyl Benzene is an organobromide compound used as an analytical reference material. It plays a key role in synthesizing various compounds, including fentanyl. When reacted with 4-piperidinone, it forms N-phenethyl-4-piperidone, a crucial precursor in fentanyl production. This precursor is classified as a List I chemical in the United States. Additionally, phenethylbromide can be found as an impurity in fentanyl produced through this synthesis route.
