CAS 64746-04-9: 1,4-Benzenedicarbonitrile,2,5-bis(bromomethyl)-

1,4-Bis(bromomethyl)-2,5-diicyanobenzene is a brominating agent used for the bromination of aromatic rings. It is an intermediate in the synthesis of other chemical compounds. The optimum reaction temperature is 100 degrees Celsius and the reaction mixture consists of 1,4-bis(bromomethyl)-2,5-diicyanobenzene and a brominating agent. Bromination reactions are carried out in an organic solvent such as dichloromethane or chloroform. Bromination reactions are slow, and the optimum reaction time is 10 minutes to 2 hours. Reactions can be monitored by spectroscopy and yield quantitative results. The product is eluted with a nonpolar solvent such as petroleum ether or hexane to isolate it from unreacted starting materials.
