Dibromofluoromethane is a mixed halomethane.{{cite web|title=Dibromofluoromethane solution|url=http://www.sigmaaldrich.com/catalog/product/SUPELCO/48077?lang=en®ion=RU|website=Sigma Aldrich|publisher=sigmaaldrich.com|access-date=7 June 2017}} It is soluble in alcohol, acetone, benzene and chloroform. It is prepared from dibromomethane and antimony(III) fluoride.{{citation|author=Bernd Baasner|date=2014|isbn=978-3-13-181544-6|pages=517|publisher=Georg Thieme Verlag|title=Houben-Weyl Methods of Organic Chemistry Vol. E 10a, 4th Edition Supplement Organo-Fluorine Compounds - Fluorinating Agents and Their Application in Organic Synthesis|url={{Google books|6y6GAwAAQBAJ||page=517|plainurl=yes}}}}

Applications

It can be used to prepare bromofluoromethane by reductive debromination with organotin hydride as tributyltin hydride.{{cite patent |country=US |number=5189229A |status=patent |title=Debrominating dibromofluoromethane with tributyltin hydride |pubdate=28 February 1989 |gdate=23 February 1993 |fdate=1 October 1990 |pridate=29 February 1989 |invent1=Robinson, John M. |assign1=Glaxo Group}}

Regulations

Its ozone depletion potential (ODP) is 1.0 and it is included in list of Class I Ozone-Depleting Substances.
