Chemical Properties

solid ingot in glass with 99.999% purity; white crystal(s); enthalpy of vaporization 41.4 kJ/mol; can be prepared readily by reacting Ge with Br2 or with GeO2 and HBr solutions [KIR78] [STR93] [CER91] [CRC10]

Uses

It is used as a chemical agent, as a laboratory chemical & for manufacturing of substances.

Safety Profile

Poison by intravenous route. When heated to decomposition it emits very toxic fumes of Br-. See also GERMANIUM COMPOUNDS.

Purification Methods

Purify it by simple distillation or fractionation depending on purity. It is soluble in EtOH, CHCl3, *C6H6 and Et2O. It fumes in moist air and is readily hydrolysed by water. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 718 1963]. LACHRYMATORY.
