Based on its physico-chemical properties it would not be expected to leach to groundwater. Biphenyl (also called Diphenyl, but exactly one of two compounds. More information on processable studies and data-waiving is available in the section help of the ‘Scientific properties’ header . Biphenyl is one of the most thermally stable of all organic compounds (HSDB, 1991). The other is o-phenylphenol, used to prevent the growth of moulds ) is an aromatic hydrocarbon; molecule structure is composed of two six-sided carbon rings connected at one carbon site on each ring.
