Description

Octafluoro-2-Butene is a fully fluorinated olefin characterized by its gaseous state and high volatility. This compound is valued in advanced industrial applications for its unique chemical inertness and specific physical properties derived from its perfluorinated structure. It serves as a critical intermediate and specialty gas in the electronics, pharmaceutical, and refrigerant industries, where high-purity fluorochemicals are essential.

Application

• Refrigerant & Heat Transfer Fluid Component: Used in the formulation of next-generation, low-global-warming-potential (GWP) refrigerants and heat transfer fluids.
• Electronics Manufacturing: Acts as a specialty etchant gas or cleaning agent in semiconductor and microelectronics fabrication processes.
• Pharmaceutical Intermediate: Serves as a key fluorinated building block in the synthesis of active pharmaceutical ingredients (APIs) and agrochemicals.
• Polymer & Material Science: Utilized as a monomer or modifier in the production of high-performance fluoropolymers with enhanced chemical and thermal resistance.
• Aerosol Propellant: Employed in specialty aerosol applications requiring non-flammable and chemically stable propellant systems.
• Laboratory Reagent: Used as a standard or reagent in analytical chemistry and research laboratories for fluorination studies.
