Fluorine

Fluorine (CAS 7782-41-4) is the most reactive of the halogen elements, supplied industrially as a compressed gas for high-demand oxidation, fluorination and surface treatment processes.

Where is Fluorine used?

• Chemical synthesis and materials processing: fluorinating agent and oxidizer
• Pharmaceutical manufacturing: introduces fluorine atoms into active pharmaceutical ingredient structures, improving metabolic stability and bioavailability
• Electronics fabrication: plasma etching and cleaning of semiconductor surfaces for chip patterning
• Mining and metals processing: fluorine-based treatment to separate and refine ore concentrates, particularly uranium and rare earth extraction
• Specialty chemicals: manufacture of fluorinated intermediates, polymers and reagents
• Fluor is a recognized commercial term in European and mining markets.

Good to know: Electronic-grade supply is subject to tighter controls. Also marketed as Fluor.

Commercial specifications

• Concentrations range from diluted mixtures to higher-purity streams
• Industrial-grade and high-purity electronic-grade specifications
• Packaging and concentration options vary by application
