methyl 1-(2-phenylethyl)-4-(N-propanoylanilino)piperidine-4-carboxylate
Carfentanil is an extremely potent synthetic opioid primarily used as an animal anesthetic. It acts as a strong μ-opioid receptor agonist and can cause severe respiratory depression even in very small amounts. Due to its high potency and toxicity, there is a significant risk of overdose and fatal poisoning. Carfentanil is not approved for human use and is associated with a high risk of abuse and dependence.
