Application

Perfluorobutane serves as a dielectric etchant gas in semiconductor fabrication for silicon and silicon nitride patterning. Its high global warming potential necessitates controlled use in closed-loop systems. In medical applications, it functions as an ultrasound contrast agent precursor due to its acoustic reflectivity and biological inertness. The compound also finds use as a tracer gas for leak detection in HVAC systems and as a stable environment for high-voltage equipment testing.
