• Description: Phenethylbromide is an analytical reference material that is structurally categorized as an organobromide. It is used in the synthesis of a variety of compounds, including fentanyl. Phenethylbromide is combined with 4-piperidinone to produce N-phenethyl-4-piperidone, which, as a precursor in the synthesis of fentanyl (Item Nos. ISO60197 | 14719), is scheduled as a List I chemical in the United States. Phenethylbromide may be found as in impurity in samples of fentanyl produced using this pathway.
• Uses: (2-Bromoethyl)benzene is used in the preparation of phenelzine by reacting with hydrazine. It is also used as a starting material to prepare various beta-phenethyl derivatives, active pharmaceutical ingredients, and fragrances. It finds application as a flame retardant.
