Sodium hypobromite is an inorganic compound with the chemical formula NaOBr. It is a sodium saltofhypobromous acid. It consists of sodium cations Na+ and hypobromite anions −OBr. It is usually obtained as the pentahydrate, so the compound that is usually called sodium hypobromite actually has the formula NaBrO·5H2O. It is a yellow-orange solid that is soluble in water. It adopts a monoclinic crystal structure with a Br–O bond length of 1.820 Å.[1] It is the bromine analogue of sodium hypochlorite, the active ingredient in common bleach. In practice the salt is usually encountered as an aqueous solution.
Sodium hypobromite arises by treatment of aqueous solution of bromine with base:[2]
It can be prepared in situ for use as a reagent, such as in the synthesis of 3-aminopyridine from nicotinamide[3] (Hofmann rearrangement).
