The IUPAC name of Ethynodiol diacetate is [(3S,8R,9S,10R,13S,14S,17R)-17-acetyloxy-17-ethynyl-13-methyl-2,3,6,7,8,9,10,11,12,14,15,16-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl]acetate. With the CAS registry number 297-76-7, it is also named as (3-beta,17-alpha)-19-Norpregn-4-en-20-yne-3,17-diol diacetate. The classification codes are Contraceptive Agents; Contraceptive Agents, Female; Contraceptives, Oral; Contraceptives, oral, synthetic; Drug / Therapeutic Agent; Hormone; Human Data; Mutation data; Progestin; Reproductive Control Agents; Reproductive Effect; Tumor data. When it is heated to decomposition, it emits acrid smoke and irritating fumes. Ethynodiol diacetate is a synthetic progestational hormone used alone or in combination with estrogens as an oral contraceptive.
