colourless liquid | [Uses]
4-Bromoanisole finds application as an intermediate in synthetic chemistry. It is used in the preparation of aryl 1,3-diketones and ethyl 4-methoxycinnamate. It is a used as a brominating reagent. Further, it is used in Suzuki coupling reaction with phenylboronic acid as well as in Heck reaction. | [Definition]
ChEBI: A monomethoxybenzene carrying a bromo substituent at position 4. | [Preparation]
4-Bromoanisole is obtained by reacting p-bromophenol with dimethyl sulfate. | [Biological Functions]
4-Bromoanisole is compound sometimes used in RNA extraction which serves to further eliminate DNA contamination. 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. | [Synthesis Reference(s)]

4-Bromoanisole is a useful brominating reagent. It is formed as reaction product in the reaction between HOBr and anisole. Suzuki coupling of 4-bromoanisole with phenylboronic acid catalyzed by palladium pincer complexes has been studied. Heck Reaction of 4-bromoanisole with ethyl acrylates in room-temperature ionic liquids is reported to afford ethyl 4-methoxycinnamate. | [Safety Profile]
Moderately toxic by ingestion andintraperitoneal routes. When heated to decomposition itemits toxic vapors of Br-. | [Purification Methods]
Crystallise the anisole by repeated partial freezing, then distil it under reduced pressure. [Beilstein 6 III 741, 6 IV 1044.] |
