Bromine solution is a chemical solution that contains elemental bromine (Br2) dissolved in water or an organic solvent. It is a reddish-brown liquid that has a pungent odor and is highly reactive. Bromine solution is primarily used as an oxidizing agent in various chemical reactions, such as the oxidation of organic compounds and the synthesis of certain pharmaceuticals and agrochemicals. It is also used as a disinfectant and water treatment agent, as well as a flame retardant in plastics and textiles. Bromine solution can be toxic and corrosive if not handled properly, and can cause skin and eye irritation upon contact.
