Sodium hypobromite is an

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]

Br2 + 2 NaOH → NaBr + NaOBr + H2O

It can be prepared in situ for use as a

3-aminopyridine from nicotinamide[3] (Hofmann rearrangement
).
