It is an unstable red-brown gas with boiling point 5°C and melting point -66 °C. Its [[CAS number]] is 13863-41-7 and its [[EINECS number]] is 237-601-4.<ref>{{Cite book |last=Gangolli |first=S. |coauthors=[[Royal Society of Chemistry]] |title=The Dictionary of Substances and Their Effects |=url=http://www.webelements.com/webelements/compounds/text/Br/Br1Cl1-13863417.html |pages=676 |date=1999 |isbn=0854048081}}</ref> It is a strong oxidizing agent. ==Uses== Bromine monochloride is used in [[analytical chemistry]] in determining low levels of [[mercury (element)|mercury]], to quantitatively oxidize mercury in the sample to Hg(II) state. Bromine monochloride is used as a [[biocide]], specifically as an [[algaecide]], [[fungicide]], and [[disinfectant]], in industrial recirculating cooling water systems. It is the active ingredient of Stabrom 909 biocide, which is used for industrial water treatment applications.<ref>{{Cite web |url=http://www.cdpr.ca.gov/docs/registration/mee/2005-41mee.htm |title=Materials Entering Evaluation Process |publisher=California Department of Pesticide Regulation |accessdate=2008-07-09 |date=2005-10-12}}</ref> Addition of bromine monochloride is used in some types of [[lithium battery|Li-SO<sub>2</sub> batteries]] to increase voltage and energy density.<ref>{{Cite web |url=http://electronic-components.globalspec.com/specifications/electrical_electronic_components/batteries/lithium_batteries |title=Battery Chemistry - Lithium / Thionyl Chloride |accessdate=2008-07-09 |publisher=GlobalSpec}}</ref> ==References== {{Reflist}} [[Category:Chlorides]] [[Category:Bromine compounds]] [[Category:Interhalogen compounds]] [[Category:Fungicides]] [[Category:Pesticides]] [[Category:Disinfectants]] [[it:Cloruro di bromo]]
