4-Fluorobenzyl bromide

4-Fluorobenzyl bromide (C7H6BrF, CAS registry No. 459-46-1) is a colorless to light yellow liquid. Its flash point is 74.8 oC. It is stable at room temperature in closed containers under normal storage and handling conditions. 1,3-Difluorobenzene can react with water to form toxic fumes. Therefore, it should be stored in a tightly closed container and should be stored in a cool, dry and well-ventilated area away from incompatible substances.

4-Fluorobenzyl bromide is an important intermediate in organic chemistry. 4-Fluorobenzyl bromide can be used as alkylating reagent to participate in the alkylation reaction with sulfamic esters (R-O-SO2-NH2) in liquid-liquid phase transfer conditions, resulting in the preparation of the N-dialkyled products or the corresponding ethers by scission of the O-SO2 bond, depending on the nature of R.
4-Fluorobenzyl bromide can be used for the synthesis of glycyrrhetinic acid (GA) derivatives, which are slow-binding inhibitors of tyrosinase and have inhibitory effects on melanogenesis.
