微溶于水；溶于甲醇、丙酮、乙醚、氯仿等有机溶剂。 4-氰基苯酚是合成血管扩张剂左色满卡林的前体。4-氰基苯酚的溴化反应可生成溴苯腈，一种商业除草剂。它也可以用作低共熔溶剂（DES）混合物的组分。 Application 4-Hydroxybenzonitrile is used as an intermediate in organic synthesis. It is also used in cosmetic as an antiseptic and disinfectant. It is involved as a raw material for the preparation of bomoxynil and ioxynil. 4-Cyanophenol is a precursor for the synthesis of a vasodilator, Levcromakalim. Bromination of 4-cyanophenol results in bromoxynil, a commercial herbicide. It can also be used as a component of deep eutectic solvent (DES) mixture.
