Perfluorobutane (PFB) is a colorless gas. It is a simple fluorocarbon with a n-butane skeleton and all the hydrogen atoms replaced with fluorine atoms. It is used as a replacement for Halon 1301 fire extinguishers,^[3] as well as the gas component for newer generation microbubble ultrasound contrast agents. Sonazoid ^[4] is one such microbubble formulation developed by Amersham Health that uses perfluorobutane for the gas core.
