Introduction
M-fluorobenzyl chloride is an organic compound. It is a colorless liquid with a pungent odor at room temperature. It is a halogenated phenylethyl hydrocarbon compound that is used as a reagent, solvent, and intermediate in chemistry.
It can be used as an intermediate in glyphosate for the preparation of pesticides such as pesticides, fungicides, and herbicides. M-fluorobenzyl chloride can also be used in the synthesis of dyes and functional materials.
The method of preparation of m-fluorobenzyl chloride can be obtained by fluorination reaction of chlorobenzene and cuprous fluoride. Specifically, chlorobenzene and cuprous fluoride are first reacted in methylene chloride, and then undergo steps such as hydrolysis, neutralization, and extraction to finally obtain the product inter-fluorobenzyl chloride.
Safety information of m-fluorobenzyl chloride: It is a toxic substance and is potentially dangerous to humans. When using or handling, safety operating procedures should be strictly followed and appropriate protective measures should be taken, such as wearing protective gloves, goggles, and protective clothing. Avoid contact with skin and eyes, and maintain a well-ventilated work environment.
