What is Krypton Difluoride CAS 13773-81-4?

Krypton difluoride, also called Krypton(II) difluoride, is an inorganic fluorine compound with CAS 13773-81-4, molecular formula F2Kr or KrF2 and molecular weight about 121.795. It is a strong oxidative fluorinating agent rather than a general-purpose industrial gas.

What is Krypton Difluoride used for?

Krypton difluoride is used in specialized inorganic fluorine chemistry, including controlled fluorination and oxidation studies. It can oxidize substrates such as gold to high oxidation states, prepare complex fluorine-containing ions, and krypton-containing mixtures are also used in specialty lamps, discharge tubes and gas adsorption measurements.

Why does Krypton Difluoride require special storage?

Krypton difluoride decomposes at room temperature and is generally stable only below about -30 °C, with long-term storage near -78 °C. It must be kept in tightly sealed, compatible containers away from moisture, reducing agents, organics and ignition sources under the supplier-specified conditions.

How should Krypton Difluoride be stored and handled?

Handle Krypton difluoride as a reactive fluorinating agent under strictly controlled conditions. Use engineered ventilation, appropriate chemical PPE and documented emergency procedures, and follow specialized low-temperature transport requirements where applicable.
