Infobox references

Perflenapent (INN/USAN), or perfluoropentane (PFP), is a fluorocarbon. 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]
