Beschreibung

Cyanophenol is a vital molecule widely used to synthesize liquid crystal materials, medicines, spices, pesticides, corrosion inhibitors, etc. Cyanophenol is formed by substituting two hydrogen atoms of benzene molecules with hydroxyl and cyano groups, respectively. The cyano and hydroxyl groups are in the ring plane in the stable molecular structure. The hydroxyl group can have two different orientations relative to the cyano group. 2-cyanophenol, one of the Cyanophenol, is an essential ingredient in pesticides, spices, liquid crystal materials, etc. It is an especially critical intermediate for synthesizing methoxyacrylate fungicide mystrostrobin, widely used in agrochemicals, pharmaceutical chemicals, and other industries. The cyano group can strongly attract electrons. Replacing a hydrogen atom of the benzene ring by the cyano group usually increases the ionization energy (IE)[1].

Chemische Eigenschaften

2-Cyanophenol is a white to light yellow crystal powder with a pungent and bitter odor. It is partially soluble in water with a Pka value of 7.17. However, it is unstable when exposed to strong alkalis and oxidants. It is an important intermediate for the synthesis of the fungicide azoxystrobin and the antihypertensive drug Bunirolol.

Verwenden

2-Hydroxybenzonitrile is used as starting reagent during the synthesis of mono-alkoxyphenyloxazoline, furanoside.

Application

2-Cyanophenol is used in the synthesis of CDK/GSK-3 inhibitors, for usage as therapeutics in Alzheimer's disease (AD).

Synthese

2-Hydroxybenzonitrile can be synthesized by condensing salicylaldehyde with hydroxylamine hydrochloride to produce salicylaldoxime. Then, the salicylaldoxime is reacted with acetic anhydride followed by hydrolysis to yield 2-Hydroxybenzonitrile.
Process for the preparation of 2-hydroxybenzonitrile

Lager

Store at 2°C - 8°C, close container well, protect from light.
