What is Cyclopropylfentanyl?

Plain description, key identifiers and synonyms

Cyclopropylfentanyl is a monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-phenyl-1-(2-phenylethyl)piperidin-4-amine with cyclopropanecarboxylic acid. It is a fentanyl analog associated with numerous overdose deaths. It has a role as an opioid analgesic and a mu-opioid receptor agonist. It is an anilide, a member of piperidines, a monocarboxylic acid amide, a tertiary amino compound and a cyclopropylcarboxamide.
