Organic Halide

Organobromides form highly reactive compounds when mixed with metals such as magnesium (Mg) or aluminum (Al); for this reason, they are used extensively in the manufacture of dyes, drugs, and other chemicals. The alkyl bromide, bromotrifluoromethane (CBrF₃) is not poisonous and will not burn. It is used in portable fire extinguishers and in airplanes to stop engine fires while in flight. Halothane (CF₃CHClBr), another organobromide, is used as a general medical anesthetic. Aryl bromides are colored and are used extensively as dyes and colorants. Alizarine Pure Blue B is an aryl bromide used to dye wool. The orange color in lipsticks is often D & C Orange No. 5, another member of the organobromide family.
