User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a fluorocarbon that is butane in which all of the hydrogens have been replaced by fluorines. Microbubbles of preflubutane are used in the ultrasound contrast agent BR14. It has a role as an ultrasound contrast agent. It is a gas molecular entity, a fluorocarbon and a fluoroalkane.
Assistant: This is a molecule that fits this description: FC(F)(F)C(F)(F)C(F)(F)C(F)(F)F
