2-Chloro-6-hydroxybenzoni... - Introduction
It is an organic compound with the chemical formula of C7H4ClNO. In the chemical structure, there is a chlorine atom and a hydroxyl group substituted for the benzene ring, and there is a nitrile group attached to the benzene ring. The compound has the solid nature of colorless or white crystals.
It is mainly used in the field of organic synthesis and medicine. It can be used as a pharmaceutical intermediate for the synthesis of other compounds, such as antibiotics, anti-tumor drugs, fungicides, etc. In addition, it can also be applied to pesticides, dyes and other fields.
The preparation can be obtained by the reaction of phenol and cuprous chloride. First, phenol is methylated with a methylenating agent under alkaline conditions to obtain 2-methoxybenzonitrile. 2-methoxybenzonitrile is then oxidized to 2-oxobenzonitrile with copper trichloride in the presence of sodium hydroxide or sodium carbonate. Finally, treatment with hydrogen chloride gives the final product.
Regarding safety information, observe general laboratory safety practices when using and storing. It is a compound that may be irritating to the eyes, skin and respiratory tract, so it is necessary to wear appropriate personal protective equipment, such as laboratory gloves, laboratory glasses and protective face masks. Avoid inhalation and contact with skin during use. If ingested or into the eyes, should immediately rinse with plenty of water, and seek the help of medical personnel.
