CAS 1207-95-0: Benzo[b]thiophene, 2-phenyl-

2-Phenylbenzo[B]thiophene is a diphenyl ether that reacts with chloride in the presence of a base to produce diphenylmethane. It has been shown to bind to estrogen receptors and can be used for the treatment of estrogen-dependent cancers. 2-Phenylbenzo[B]thiophene has been shown to have anti-estrogenic properties, which may be due to its ability to compete with estrogen at the receptor binding site. In addition, it is a radical chain compound that can undergo reactions involving oxygen or nitrogen radicals. The nature of these reactions depends on the reaction products involved in the reactions. 2-Phenylbenzo[B]thiophene can react with xanthates such as diethylxanthate to produce pharmaceutical preparations such as phenyltriethyleneglycolxanthate and phenyldiethoxymethoxyethyleneglycolxanthate.
