Preparation and properties

4-Vinylcyclohexene dioxide is prepared by epoxidation of 4-vinylcyclohexene with peroxybenzoic acid.[5] Its viscosity is 15 mPa·s.[5]

Safety

4-Vinylcyclohexene dioxide, like other volatile epoxides, is classified as an alkylating agent.[5] VCD has toxic effects on fertility. It is a killer of oocytes in immature ovarian follicles in mice and rats.[7][8][9]

In pest control, it has been used as an ovotoxic agent for reducing rat fertility.[10]

gollark: 150WPMish.
gollark: Faster than that, I think?
gollark: Sometimes I plug my phone into my computer and use `scrcpy` to type unreasonably fast on it, for text conversations.
gollark: I thought it was 115. Oh no.
gollark: It's probably because something something access to paper/computers for temporary storage.
