Products Description
(2‑Bromoethyl)benzene, CAS#103‑63‑9, also known as phenethyl bromide, is an organobromide‑type analytical reference standard. It serves as a building‑block reagent for synthesizing multiple chemical compounds, fentanyl included. The reaction between phenethyl bromide and 4‑piperidinone yields phenethyl‑4‑piperidone, a key precursor for fentanyl production which is categorized as a List I chemical under US regulations. Trace amounts of phenethyl bromide can remain as an impurity in fentanyl batches prepared through this synthetic pathway.
