Estra-1,3,5(10),7-tetraen-17-one, 3-hydroxy-, cyclic 1,2-ethanediyl acetal is a complex organic compound with the chemical formula C20H24O3. It is a derivative of estrone, a naturally occurring steroid hormone and a precursor to estradiol, which plays a crucial role in the female reproductive system. This specific compound is characterized by the presence of a cyclic 1,2-ethanediyl acetal group, which is formed by the reaction of the hydroxyl group at the 3-position with two molecules of ethylene oxide. The cyclic acetal structure provides increased stability and solubility compared to the parent estrone molecule. Estra-1,3,5(10),7-tetraen-17-one, 3-hydroxy-, cyclic 1,2-ethanediyl acetal has potential applications in pharmaceuticals and research, particularly in the development of hormone therapies and understanding the mechanisms of steroid hormone action.
The CAS Registry Mumber 64-22-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 4 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 64-22: (4*6)+(3*4)+(2*2)+(1*2)=42 42 % 10 = 2 So 64-22-2 is a valid CAS Registry Number.
