Chemistry & industry
Pharmacology
MeSH Pharmacological Classification
Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.
Applications
Uses(S)-(-)-Styrene oxide can undergo copolymerization with CO2 to form the corresponding polycarbonate in the presence of a cobalt-based catalyst system.
General DescriptionStyrene oxide is an oxirane derivative, which is used as a monomer for the synthesis of polyesters with relatively highTg values via ring-opening copolymerization. It can also be used as a useful intermediate in the preparation of levamisole, a nematocideand anticancer agent.
