Biphenyl (or diphenyl or phenylbenzene or 1,1′-biphenyl or lemonene) is an organic compound that forms colorless crystals.
It has a distinctively pleasant smell. Biphenyl is an aromatic hydrocarbon with a molecular formula (C6H5)2. It is notable as a starting material for the production of polychlorinated biphenyls (PCBs), which were once widely used as dielectric fluids and heat transfer agents.
Biphenyl is also an intermediate for the production of a host of other organic compounds such as emulsifiers, optical brighteners, crop protection products, and plastics. Biphenyl is insoluble in water, but soluble in typical organic solvents. The biphenyl molecule consists of two connected phenyl rings.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Lepomis macrochirus (Bluegill) 4.7 mg/L/96 hr (95% confidence interval: 4.3-5.1 mg/L); static
  • Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna (Water flea; intoxication, immobilization) 7.1 mmol/cu m/48 hr; static
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Several organisms have been found that can grow on diphenyl and use it as the sole carbon source.

12.3 Bioaccumulative potential

Bioconcentration factors for biphenyl in golden orfe (Leuciscus idus melanotus) and the amphipod Rhepoxynius abronius, have been measured as 280(1) and 4,500(2). Measured BCF values for rainbow trout (Salmo gairdneri) were reported as 437(3) and 1,318(4). According to a classification scheme(5), these BCF values indicate that bioconcentration in aquatic organisms is high to very high(SRC). Bivalve molluscs, Mercenaria mercenaria L., exposed to waste crankcase oil containing biphenyl for 2 days, did not significantly depurate biphenyl over a 45 day period in clean water(6).

12.4 Mobility in soil

In three soils, the log Koc was determined to be in the range 2.94-3.52 (Koc of 871-3,331)(1). The experimental mean log Koc value in five soils was 3.16 (Koc of 1,445)(3). The log Koc value in humic acids was determined to be 3.27 (Koc of 1,862)(4). According to a recommended classification scheme(2), these log Koc values indicate biphenyl may have low to slight mobility in soil(SRC). A log Koc of 5.09 was measured using soot columns and an SRM-1650 soot standard obtained from NIST(5). A retardation factor (Rf) of 2.1 was measured for biphenyl using soil columns filled with a surface soil (organic carbon = 12.6%, 60.3% sand, 24.0% silt, 15.7% clay, porosity = 0.7)(6). A retardation factor of 2.2-2.3 was measured for biphenyl on columns packed with low carbon aquifer material(7). The sorption of biphenyl on HDTMA clays indicated that sorption occurs via partition interactions with the HDTMA-derived organic phase. The greater the HDTMA content and the larger spacings of high charge HDTMA clays increased biphenyl's sorption(8).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
