(2-Bromoethyl)benzene CAS 103-63-9 Application

β- Bromophenylethane is an important intermediate for the synthesis of high-efficiency brominated flame retardant polybrominated styrene, and it is also often used in the preparation of organic synthesis intermediates. as β- Bromophenylethane can be used to prepare 4- (4-phenylbutoxy) benzoic acid, the intermediate of pranlenist. As an anti asthmatic drug, pranlenist was successfully developed by Ono company in Japan for the first time, and was listed in Japan in 1995. In 1999, it was found that it can treat allergic rhinitis. Pravist is a leukotriene c4/d4 receptor antagonist (LTRAs) with extremely low toxicity. It can selectively inhibit the activity of leukotriene polyskin in airway smooth muscle, has little effect on arachidonic acid metabolic enzymes, has no antagonistic effect on acetylcholine, 5-hydroxytryptamine, and has significant inhibition on LTC4, LTD4, LTE4, etc.
