Pregn-5-ene-3,20-dione bis(ethylene ketal) is a chemical compound with the molecular formula C23H36O4. It is a derivative of pregnane, a steroid with a five-carbon ring structure. The compound is characterized by the presence of two ethylene ketal groups, which are formed by the reaction of the carbonyl groups at positions 3 and 20 with ethylene oxide. This modification helps to stabilize the molecule and protect the carbonyl groups from unwanted reactions. Pregn-5-ene-3,20-dione bis(ethylene ketal) is used in various applications, including pharmaceuticals and chemical research, due to its unique structure and properties.

7093-55-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7093-55-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7093-55:
(6*7)+(5*0)+(4*9)+(3*3)+(2*5)+(1*5)=102
102 % 10 = 2
So 7093-55-2 is a valid CAS Registry Number.

Production process capable of industrially synthesizing dydrogesterone

-

Paragraph 0039-0041, (2020/03/03)

The invention discloses a production process capable of industrially synthesizing dydrogesterone. Easily available progesterone is used as a raw material, and dydrogesterone is prepared through the steps of carbonyl protection, bromination, debromination, photochemical ring-opening reaction, photochemical ring-closing reaction, deprotection and double bond isomerization. The production process hasthe advantages of easily available initial raw materials, and easiness in implementation of each step and higher yield; the production process is simple and convenient to operate, is green and environment-friendly, and can be easily amplified to industrial production.

CHEMOSELECTIVE ETHYLENE ACETALIZATION OF α,β-UNSATURATED vis-a-vis SATURATED CARBONYL GROUPS

Nitz, Theodore J.,Paquette, Leo A.

, p. 3047 - 3050 (2007/10/02)

The difficulties which in the past have precluded controlled acetalization of an α,β-unsaturated ketone functionality in the presence of a saturated carbonyl group can be overcome simply by making recourse to 2,4,6-collidinium p-toluenesulfonate as catalyst.
