Bromine is a non-metallic, reddish brown colored chemical that exists in a liquid state at room temperature. It is volatile, highly toxic, and belongs to the halogen family. Bromine is used to synthesize three major derivatives including organobromine, clear brine fluid, and hydrogen bromide or hydrobromic acid. These derivatives along with their parent compound liquid bromine are used in a variety of applications. The major applications include flame retardants, drilling and completion fluids, biocides, chemicals used in water treatment, pharmaceuticals, plasma etching and PTA (Purified Terephthalic Acid) synthesis. One of the salts of bromine known as sliver bromide is extensively used in photography.
