Alfentanil is a restricted drug which is classified as Schedule II in the US, according to the U.S. DEA website. Alfentanil is a potent but short-acting synthetic opioid analgesic drug, used for anaesthesia in surgery. It is an analogue of fentanyl with around 1/4 to 1/10 the potency of fentanyl and around 1/3 of the duration of action, but with an onset of effects 4x faster than fentanyl. Reference standards of Alfentanil API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
