Allgemeine Beschreibung

Styrene oxide is an oxirane derivative, which is used as a monomer for the synthesis of polyesters with relatively high Tg values via ring-opening copolymerization. It can also be used as a useful intermediate in the preparation of levamisole, a nematocide and anticancer agent.

Anwendung

(S)-(-)-Styrene oxide can undergo copolymerization with CO2 to form the corresponding polycarbonate in the presence of a cobalt-based catalyst system.

Vorsicht

Product should be sampled and packaged in a glove bag under nitrogen.

The cytogenetic alterations in leukocytes and the increased risk for leukemia, lymphoma, or all lymphohematopoietic cancer observed in workers occupationally exposed to styrene have been associated with its hepatic metabolisation into styrene-7,8-oxide, an epoxide which can induce DNA damages.

Styrene induces lung tumors in mice but not in rats. Although metabolism of styrene to 7,8-styrene oxide (SO) by CYP2E1 has been suggested as a mediator of styrene toxicity, lung toxicity is not attenuated in CYP2E1 knockout mice. However, styrene
