Chemical compound

Sodium bromite is a sodium salt of bromous acid. Its trihydrate, NaBrO₂·3H₂O, has been isolated in crystal form. It is used by the textile refining industry as a desizing agent for oxidative starch removal.

It is also used as an oxidizing agent for converting alcohols to aldehydes, such as the conversion of benzyl alcohol to benzaldehyde, and for the Hofmann degradation of amides to amines.
