What is Ocfentanil?

Plain description, key identifiers and synonyms

Ocfentanyl is a monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-(2-fluorophenyl)-1-(2-phenylethyl)piperidin-4-amine with methoxyacetic acid. It is a synthetic analogue of fentanyl. It has a role as an opioid analgesic and a mu-opioid receptor agonist. It is an ether, a member of piperidines, a monocarboxylic acid amide, a tertiary amino compound and a member of monofluorobenzenes.
