Used primarily in the textile industry as an oxidizing agent for dyeing and finishing processes, especially in the bleaching of wool and silk. It helps achieve consistent color and improved fabric quality. Also employed in the manufacture of other bromine compounds and in some hair-waving preparations as a permanent wave agent due to its ability to break and reform disulfide bonds in keratin. Its use in cosmetics is strictly regulated due to potential toxicity and health risks. In analytical chemistry, it serves as a reagent in titrations (e.g., bromatometry for reducing agents like arsenites) and oxidation reactions. Historically used as a flour improver to enhance dough strength and bread texture, though this application is now restricted or banned in many countries due to health concerns.
