Health HazardACUTE/CHRONIC HAZARDS: When heated to decomposition Ethynyl estradiol emits acrid smoke and fumes.
Fire HazardThe flash point data for Ethynyl estradiol are not available. Ethynyl estradiol is probably combustible.
Purification Methods17--Ethynylestradiol forms a hemihydrate on recrystallising from MeOH/H2O. It dehydrates on melting and remelts on further heating at m 182-184o. The UV has max at 281nm ( 2040) in EtOH. Its solubility is 17% in EtOH, 25% in Et2O, 20% in Me2CO, 25% in dioxane and 5% in CHCl3. [Petit & Muller Bull Soc Chim Fr 121 1951.] The diacetyl derivative has m 143-144o (from MeOH) and [] D 20 +1o (c 1, CHCl3) [Mills et al. J Am Chem Soc 80 6118 1958]. [Beilstein 6 IV 6877.]
