Products scope: Alcohols and Derivatives; Steroids;Acetylenes;Biochemistry; Functionalized Acetylenes; Hydroxysteroids; Intermediates & Fine Chemicals ;Metabolites & Impurities; Pharmaceuticals Usage Ethinyl estradiol (EE), also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl estradiol, is aderivative of 17 beta-estradiol (E2), the major endogenous estrogen in humans. EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is one of the most commonly used medications for this purpose. Transdermal ethinyl estradiol carries a greater risk of clot formation and venous thromboembolism than naturally occurring 17β-estradiol, which some have theorized to be related to different amounts of hepatic metabolism after absorption. The same contraindications and precautions apply for EE as with other estrogen medications. Applications Ethynyl estradiol, as a pharmaceutical raw materials. It can be used as a synthetic steroid with high oral estrogenic potency Packaging Detail 25kg/Fiber drum--Inner double plastic bags, 5kg/Aluminum foil bag -- Inner double plastic bags,1kg/Aluminum foil bag--Inner double plastic bags Storage Store in a well-closed container away from moisture Shelf Life 2 years if sealed and store away from direct sun light.
