Bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table ( halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a simi ...
monochloride, also called bromine(I) chloride, bromochloride, and bromine chloride, is an
interhalogen
In chemistry, an interhalogen compound is a molecule which contains two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group.
Most interhalogen compounds known are binar ...
inorganic compound with chemical formula BrCl. It is a very reactive golden yellow 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. It is a strong oxidizing agent.
Uses
Bromine monochloride is used in
analytical chemistry in determining low levels of
mercury, to quantitatively oxidize mercury in the sample to Hg(II) state.
A common use of bromine monochloride is as an
algaecide,
fungicide, and
disinfectant
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than s ...
of industrial recirculating cooling water systems.
Addition of bromine monochloride is used in some types of
Li-SO2 batteries to increase voltage and energy density.
