Bromotrifluoromethane

Bromotrifluoromethane, commonly known as Halon 1301, R13B1, Halon 13B1 or BTM, is an organic halide with the chemical formula CBrF₃. It is used for fire suppression and refrigeration. Human exposure to Halon 1301 can be toxic, affecting the central nervous system and other bodily functions. Additionally, it is known to contribute to the depletion of Earth's atmospheric ozone layer when released. As such Halon's use as a refrigerant has been virtually eliminated and alternatives are being used increasingly for fire suppression.
