Sulfuryl Fluoride - The Industry Standard
Unlike liquid pesticides that rely on surfactants and inert carriers, Sulfuryl Fluoride is a consistent chemical compound. ZYTHOR® delivers over 99% pure SO2F2, providing the same active ingredient you’ve trusted for decades.
Why choose ZYTHOR® Structural Gas Fumigant?
Over 99% Pure Sulfuryl Fluoride
Sulfuryl Fluoride is not a proprietary formulation with unique attributes; Once the cylinder is opened and the liquid turns to gas, all SO2F2 behaves identically according to the laws of physics.
