What is 2-Phenylphenol and where is it found: This chemical is used in the manufacture of dyes and resins, rubber chemicals, fungicides, germicides, preservatives and food packaging. It is used as a disinfectant and fungicide for impregnation of fruit wrappers and seed boxes. It can also be found in household disinfectants, some cosmetics, cooling fluids and detergents. Further research may identify additional product or industrial usages of this chemical.

2-Phenylphenol (CAS No. 90-43-7) is used as a disinfectant, bactericide and virucide. In agriculture, it is used in disinfecting fruits, vegetables and eggs. It is also used as a general surface disinfectant in hospitals, nursing homes, veterinary hospitals, poultry farms, dairy farms, commercial laundries, barbershops and food processing plants. 2-Phenylphenol is readily degraded in surface waters, with a half-life of about 1 week in river water. 2-Phenylphenol has been determined to be of low toxicity. Both 2-phenylphenol and its sodium salt are carcinogenic in male rats, and 2-phenylphenol is carcinogenic in male mice. However, urinary bladder tumours observed in male rats and liver tumours observed in male mice exposed to 2-phenylphenol appear to be threshold phenomena that are species- and sex-specific. JMPR has concluded that 2-phenylphenol is unlikely to represent a carcinogenic risk to humans. Although a working group convened by IARC has classified 2-phenylphenol, sodium salt, in Group 2B (possibly carcinogenic to humans) and 2-phenylphenol in Group 3 (not classifiable as to its carcinogenicity to humans), JMPR noted that the IARC classification is based on hazard identification, not risk assessment, and is furthermore limited to published literature, excluding unpublished studies on toxicity and carcinogenicity. JMPR also concluded that there are unresolved questions about the genotoxic potential of 2-phenylphenol.

Local:  Phenylphenol is used in formulating biocides and preservatives. It can be used as a additive for food packaging materials, seed boxes and household goods as a disinfectant and fungicide. Phenylphenol is used to manufacture germicide, fungicide, rubber chemicals and dyes.

GENERAL DESCRIPTION OF BIPHENYL: Biphenyl (also called Diphenyl, but exactly one of two compounds. 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. Pure biphenyl is a toxic colourless crystalline solid with a pleasant odour; melting point 70 C, boiling point 255 C, which gives plates or monoclinic prismatic crystals; it is insoluble in water but soluble in ordinary organic solvents. It is directly used in the preservation of citrus fruits  as a fungistat in transportation containers. It is a raw material for polychlorinated diphenyls (PCB) in which chlorine replaces hydrogen in biphenyls. There are 209 chlorinated isomers of biphenyl theoretically. But PCBs are referred to the biphenyl compounds with one to ten chlorine substitutions. PCBs are used heat-transfer agents and as electric insulators that block the flow of electric current across in electrical equipments. They are known as environmental pollution materials which are accumulated in animal tissues and cause toxic effects including carcinogenesis. Biphenyl is used as an intermediate for the production of a wide range of organic compounds (e.g. emulsifiers, optical brighteners, crop protection products, plastics), as a heat transfer medium alone or with diphenyl ether in heating fluids, as a dyestuff carrier for textiles and copying paper and as a solvent in pharmaceutical production. Aminodiphenyls are used as rubber antioxidants and intermediates for the synthesis of organic compounds ( azo dyes and pharmaceuticals). Biphenyl derivatives are used as an intermediate for the synthesis of organic compounds including pharmaceuticals, antifungal agents, optical brightening agents and dyes. Biphenyl compounds also used in luminescence chemistry, spectrophotometric analysis, molecular chemistry, and as a stating material for organometallic-complexes.
