3496-78-4

(5α,6α)-Epoxy-17α-hydroxy-pregnane-3,20-dione-3,20-bis(ethyleneketal) is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid with a specific carbon skeleton. The compound is distinguished by the presence of an epoxy group at the 5α,6α positions, a hydroxyl group at the 17α position, and a dione group at the 3,20 positions. The 3,20-dione group is further protected by a bis(ethyleneketal) moiety, which is a derivative of ethylene glycol that forms a cyclic acetal with the carbonyl groups. (5α,6α)-Epoxy-17α-hydroxy-pregnane-3,20-dione-3,20-bis(ethyleneketal) is of interest in the field of organic chemistry, particularly in the synthesis of complex steroidal molecules and may have potential applications in pharmaceuticals due to the diverse biological activities of steroids.

3496-78-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3496-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3496-78:
(6*3)+(5*4)+(4*9)+(3*6)+(2*7)+(1*8)=114
114 % 10 = 4
So 3496-78-4 is a valid CAS Registry Number.

Preparation method of palace progesterone

-

Paragraph 0115; 0117; 0124; 0126; 0131; 0133; 0138-0141, (2021/11/03)

The invention relates to the technical field of preparation of pharmaceutical active pharmaceutical chemicals, in particular to a preparation method of palace progesterone. To the preparation method, 17 α - hydroxyl progesterone is used as a substrate, and nucleophilic addition reaction is carried out in sequence. An epoxidation reaction, an open-loop addition reaction, an elimination reaction, an esterification reaction and a hydrolysis reaction are adopted to obtain the toecliptin progesterone, and a precious metal catalyst and a carcinogenic solvent are not used in the preparation process simultaneously. ≥ 91%.
