| General description: | 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. |
