| Ethynyl estradiol Usage And Synthesis |
| Chemical Properties | Off-White to Light-Yellow Crystalline Powder |
| Uses | A metabolite of 17a-Ethynylestradiol |
| Uses | A synthetic steroid with high oral estrogenic potency |
| Uses | estrogen, plus progestogen as oral contraceptive |
| Uses | A synthetic estradiol analog. |
| Definition | ChEBI: A 3-hydroxy steroid that is estradiol substituted by a ethynyl group at position 17. It is a xenoestrogen synthesized from estradiol and has been shown to exhibit high estrogenic potency on oral administration. |
| General Description | Fine white to creamy white powder. A synthetic steroid. Used in combination with progestogen as an oral contraceptive. |
| Air & Water Reactions | Air and light sensitive . Insoluble in water. |
| Reactivity Profile | Ethynyl estradiol may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to generate gaseous hydrogen. |
| Health Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition Ethynyl estradiol emits acrid smoke and fumes. |
| Fire Hazard | The flash point data for Ethynyl estradiol are not available. Ethynyl estradiol is probably combustible. |
