| 4-Cyano-4'-pentylbiphenyl Usage And Synthesis |
| Chemical Properties | white to light yellow crysta |
| Uses | 4-Cyano-4'-n-pentylbiphenyl is used in the preparation of 4'-pentylbiphenyl-4-carboxylic acid by acidic hydrolysis using sulfuric acid as a reagent. |
| Uses | Intermediates of Liquid Crystals |
| General Description | 4′-Pentyl-4-biphenylcarbonitrile (5CB) is a nematic liquid crystal. 5CB undergoes phase transition from crystalline to nematic then to isotropic state at 18oC and 35oC respectively. It may be produced by modifying biphenyl.2 |
