use	for organic synthesis.
Production method	It is obtained by the reaction of p-xylene and bromine. Paraxylene was heated to 120 ℃, and bromine was added to stir the reaction under strong light. Bromohydroacid is removed after the reaction. The reaction product is dried and then distilled under reduced pressure to obtain 4-methyl bromide.
