General description

4-Chlorodiphenyl ether is halogenated diphenyl ether. It is an estrogenic contaminant and its effect on the growth of endometrial implants has been investigated. Dehalogenations of 4-chlorodiphenyl ether at 375°C over CaO/Ca(OH)2 has been reported.

Application

4-Chlorodiphenyl ether can be used in the preparation of 4′-chloro-2,2′,3,3′,4,5,5′,6,6′-nonabromodiphenyl ether (Cl-BDE-208), an internal standard used in the analysis of highly brominated diphenyl ethers.

The metabolic disposition of 14C-labeled 4-chlorodiphenyl ether ([14C]4-CDE) was examined in rats following iv administration of a single dose (850 nmol/kg). [14C]4-CDE decayed rapidly from the blood since no unchanged [14C]4-CDE was detected in the blood beyond 2 hr after

Polybrominated diphenyl ethers (PBDEs) have been used extensively as brominated flame retardants (BFRs) in textiles, upholstery and electronics. They are ubiquitous contaminants in wildlife and humans. A low concentration of nonabrominated diphenyl ethers (nonaBDEs) is present in commercial DecaBDE and
