Estrone 17-Ethylene Ketal is a synthetic derivative of the naturally occurring hormone estrone, which is a type of estrogen. It is a white crystalline powder with the chemical formula C20H26O2. Estrone 17-Ethylene Ketal is formed by the reaction of estrone with ethylene oxide, resulting in the formation of a cyclic ketal group at the 17-position of the estrone molecule. Estrone 17-Ethylene Ketal is used in pharmaceutical applications, particularly in the development of hormone replacement therapies and contraceptives, due to its ability to mimic the effects of natural estrogen in the body. It is also used in research to study the effects of estrogen on various physiological processes. The compound is known for its stability and slower rate of metabolism compared to estrone, which can make it a more effective and longer-lasting option in certain medical applications.

900-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 900-83-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 900-83:
(5*9)+(4*0)+(3*0)+(2*8)+(1*3)=64
64 % 10 = 4
So 900-83-4 is a valid CAS Registry Number.

Selective rhenium-catalyzed oxidation of secondary alcohols with methyl sulfoxide in the presence of ethylene glycol, a convenient one-pot synthesis of ketals

Arterburn, Jeffrey B.,Perry, Marc C.

, p. 769 - 771 (2008/02/12)

Formula presented Secondary alcohols are oxidized preferentially by DMSO and the catalyst ReOCl3(PPh3)2 in the presence of ethylene glycol and refluxing toluene, producing the corresponding ketals. The reactions are rapid, and proceed in very good to excellent yields. The byproducts of the reaction, methyl sulfide and water, are easily removed. No epoxidation or other common side reactions were observed. This direct oxidative transformation of alcohols to the protected ketal derivatives should have broad synthetic applicability.
