Carfentanil

Carfentanil or carfentanyl is an analog of the synthetic opioid analgesic fentanyl. A unit of carfentanil is 100 times as potent as the same amount of fentanyl, 5,000 times as potent as a unit of heroin and 10,000 times as potent as a unit of morphine. Carfentanil was first synthesized in 1974 by a team of chemists at Janssen Pharmaceutica which included Paul Janssen. It is classified as Schedule II under the Controlled Substances Act in the United States with a DEA ACSCN of 9743 and a 2016 annual aggregate manufacturing quota of 19 grams (less than 0.7 oz.). It was used as a tranqualizer for the dinosaurs of Isla Nublar and Isla Sorna
