Chemistry & industry
Pharmacology
Metabolism/Metabolites
Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)

Applications
DescriptionLithium bromide (LiBr) is the chemical compound of lithium and bromine. It has extreme hygroscopic, making it a suitable desiccant in the air conditioning systems. It can also be used in absorption chilling together with water. It is also useful in the organic synthesis such as forming adduct with some pharmaceuticals. In medical fields, it can be used as a sedative and used for the treatment of bipolar disorder. It can be manufactured by the treatment of lithium carbonate with hydrobromic acid.
UsesLithium bromide is used in absorption, refrigeration and air-conditioning systems. A highly concentrated solution of the salt is an efficient absorbent of water vapor. The vapor pressure of such solution is very low. Other applications include the use of the salt as a swelling agent for wool, hair and other organic fibers; as a catalyst in dehydrohalogenation reactions; and as a sedative and hypnotic in medicine.
