 |  | [Definition] 
 ChEBI: 4-cyanophenol is a member of phenols. It has a role as an EC 1.4.3.4 (monoamine oxidase) inhibitor. It is functionally related to a benzonitrile.
 |  | [Preparation] 
 4-Cyanophenol is produced by reaction of 4-bromophenol with copper (I) cyanide, by ammoxidation of p-cresol, by reaction of 4-chlorobenzonitrile with sodium methoxide, or by the catalyzed gas phase reaction of ethyl 4-hydroxybenzoate with ammonia.

 |  | [Purification Methods] 
 Crystallise the phenol from pet ether, *benzene or water and keep it under vacuum over P2O5. [Bernasconi & Paschelis J Am Chem Soc 108 2969 1986.] [Beilstein 10 H 167, 10 IV 441.]
