Description
Perfluoroisobutylene (PFIB) is a schedule 2A substance under
the Chemical Weapons Convention, which means that while it
has significant ability to be used as a chemical weapon, it also
serves various other industrial uses.

Uses
Perfluoroisobutylene or perfluoroisobutene is a monomer used
in synthesis of Teflon and other polymeric materials. It is also
used in etching for semiconductor fabrication, and is potentially
used as a chemical warfare agent. The US Food and Drug
Administration’s CFR 21 Section 173.360 allows for use of
octafluorocyclobutane as a propellant and also allows for PFIB
at a level of <.01% as an impurity in formulation.
