4-Bromoanisole is the organobromine compound with the formula CH₃OC₆H₄Br. It is colorless liquid with a pleasant smell similar to that of anise seed. It is one of three isomers of bromoanisole, the others being 3-bromoanisole and 2-bromoanisole. It is the precursor to many 4-anisyl derivatives.

Reactions and uses

4-Bromoanisole forms a Grignard reagent,[1] which reacts with phosphorus trichloride to give tris(4-methoxyphenyl)phosphine:

3 CH₃OC₆H₄MgBr + PCl₃ → (CH₃OC₆H₄)₃P + 3 MgBrCl

4-Bromoanisole forms the organozinc derivative CH₃OC₆H₄ZnBr.[2]

4-Bromoanisole is compound sometimes used in RNA extraction which serves to further eliminate DNA contamination.[3] It interacts with genomic DNA (gDNA) and through a separation phase, it will be located in the organic layer instead of the aqueous layer (upper layer) containing the RNA extract.[4]
