Introduction

3,4-Difluorobenzonitrile is an organic compound. The following is an introduction to its properties, uses, manufacturing methods and safety information:Quality:3,4-Difluorobenzonitrile is a colorless to pale yellow solid with a specific chemical structure. It has a strong volatile and pungent odor. The compound is stable at room temperature and pressure.Use:3,4-Difluorobenzonitrile has certain uses. It is often used in organic synthesis reactions as an important intermediate of nitrile compounds. It can also be used as a raw material for pesticides, pesticides, dyes, and fluorescent brighteners, among others.Method:3,4-Difluorobenzonitrile is usually prepared by the reaction between benzonitrile and fluoride. A common preparation method is to react benzonitrile with boron trifluoride (BF3) or boron trichloride (BCl3) in an appropriate solvent, add sodium fluoride (NaNF2) or other fluoride, and adjust the reaction conditions to obtain the desired product.Safety Information:- 3,4-Difluorobenzonitrile is irritating and corrosive, so avoid direct contact with skin and eyes.- During operation, ensure adequate ventilation to avoid inhalation or exposure to vapors.- Store in an airtight container, away from heat and fire.
