Perflenapent (INN/USAN; also known as perfluoropentane (PFP) and dodecafluoropentane) is a fluorocarbon, the fluorinated analogue of pentane. It is a liquid that boils at slightly over room temperature.

It has several biomedical applications including: propellant for pressurized metered dose inhalers;[3] gas core in microbubble ultrasound contrast agents;[4] and occlusion therapy via the conversion of nanometer liquid droplets into micrometer sized gas microbubbles (acoustic droplet vaporization).[5]
