Bromine is used in many areas such as:
- dyestuffs: Bromine-Containing Pigment Dyes Of The Perinone Series (1970),
- insecticides: 5-bromomethyl-hexachloro-bicyclo-[2, 2, 1]-heptene-(2) insecticide (1964), and
- disinfectant detergents in agriculture , medicine and food: Alkali Metal Polyphosphate-Bromine-Containing Complexes And Production Thereof (1976).
Bromine compounds can be used as flame retardants: Alkali Metal Polyphosphate-Bromine-Containing Complexes And Production Thereof (1965). They are added to furniture foam, plastic casings for electronics and textiles to make them less flammable.
Silver bromide has been used for more than a century in photography: Collodion Silver Bromide Instantaneous Photographic Plate and its Method of Manufacture (1911).
Before leaded fuels were phased out, bromine was used to prepare 1,2-di-bromoethane, (“ethylene dibromide”) (Antiknock Compounds (1931)), which was an anti-knock agent in conjunction with other chemicals.
