English name: biphenyl 
CAS No.: 92-52-4 
Molecular formula: C12H10 
Molecular weight: 154.21 
content: 99.90% 
Physicochemical properties: 
colorless or light yellow, flaky crystals, slightly sweet smell. Melting point (°C): 69.71 boiling point (°C): 254.25

Uses:
Because of its high thermal stability and low vapor pressure, biphenyl has long been used alone or as a heat carrier after mixing with diphenyl ether. The industrially widely used derivative A is a eutectic mixture composed of biphenyl and diphenyl ether in a mass ratio of 26.5:73.5, which can be used in the temperature range of 12 to 400 ° C, but the temperature range commonly used in industry. It is 250 to 360 °C. Shandu Wax, which consists of biphenyl, terphenyl, etc. (13% by mass of biphenyl and 61% of terphenyl) can effectively absorb radiation and is suitable as a heat carrier for nuclear power plants. And terphenyl is just a by-product of the pyrolysis of biphenyl to benzene. Another major use of biphenyl is as a dyeing agent in the printing and dyeing industry and as an impregnant for citrus packaging paper.
