Biphenyl

Biphenyl (pronounced: bih-fen-uhl) is a simple aromatic hydrocarbon with the formula (C6H5)2. This colorless solid is notable for its pleasant smell. The compound is widely used as an intermediate in the production of a variety of other chemicals.

Etymology

The term "biphenyl" is derived from the Greek words "bi", meaning two, and "phenyl", referring to the phenyl group (C6H5) in chemistry.

Chemical Structure

Biphenyl consists of two connected phenyl rings. The two rings of a biphenyl molecule can rotate around the single bond that connects them, resulting in a variety of different conformations.

Uses

Biphenyl is used in organic syntheses, heat transfer fluids, dye carriers, food preservatives, as an intermediate for polychlorinated biphenyls, and as a fungistat in the packaging of citrus fruits.

Health Effects

Exposure to biphenyl can cause eye irritation and skin burns. Ingestion can result in burning sensation, abdominal pain, dizziness, sedation, and nausea. Chronic exposure may lead to liver and kidney damage.
