| Physical and Chemical Properties | 3-bromobenzyl alcohol is colorless transparent liquid at room temperature and atmospheric pressure. In the conversion of organic synthesis, the bromine atom in the structure can be subjected to arylation reaction or alkylation reaction by coupling, and the bromine atom can also be converted into a boric acid unit, then the subsequent transformation is carried out by means of the diversity transformation property of boron units. In addition, the hydroxyl unit in the structure can be converted into aldehyde group or carboxyl group under the action of oxidant; hydroxyl groups can also be converted to halogen atoms by halogenation |

Benzenemethanol, 3-bromo- - Reference Information
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Use | 3-bromobenzyl alcohol belongs to benzyl alcohol derivatives, which can be used as fixatives, such as jasmine, moonrise, in the synthesis of essence and fragrance such as Ilan, it can also be used as an intermediate in organic synthesis. |
| synthetic method | sodium hydride (0.0044g, 10 mol%), A dry reaction flask was charged with a mixture of cysterolborane (0.17 ML, 1.2 mmol) and 5 ml of tetrahydrofuran, and the flask was replaced with argon and fitted with a magnetic stir bar. The corresponding aldehyde (0.1 mL,1.0 mmol) was slowly added dropwise to the reaction mixture, and the mixture was stirred at room temperature for 30 min. Quench to stop the reaction, then add 1N sodium hydroxide (2 ml) to the reaction mixture, and stir the resulting mixture at room temperature (25-27 °c) for 1 hour, the crude mixture was extracted with diethyl ether (2 x 10 mL) and finally the combined organic layers were dried over anhydrous magnesium sulfate to give the target product 3-bromobenzyl alcohol.
