Ethynodiol diacetate Usage And Synthesis
Uses anticonvulsant
General Description Ethynodiol diacetate, 19-norpregn-4-en-20-yne-3β,17α-diol diacetate, is a prodrug ofnorethindrone. A combination of hydrolysis of both estersand oxidation of the C3 alcohol to the ketone is necessary toprovide the fully active progestin.
Safety Profile Suspected carcinogen. Human reproductive effects by ingestion: menstrual cycle changes. Experimental reproductive effects. Mutation data reported. A steroid. When heated to decomposition it emits acrid smoke and irritating fumes.
