1,2-Dibromotetrafluoroethane (C2Br2F4) is a haloalkane. It is also known under codenames R-114B2 and Halon 2402. It is a colorless liquid with a boiling point of 47.2 °C. R-114B2 is occasionally used in fire suppression systems. It is also used as a tracer chemical in Praxair's Seep Sense leak detection system. It is highly volatile, passes through soil to air, and allows detection in the parts-per-quadrillion range.[2]

On November 8, 2008, an accident aboard Russian submarine K-152 Nerpa due to unintentional activation of a fire suppressant system loaded with R-114B2 killed 20 people and injured 21 more.[3]
