Urs-12-en-28-oic acid, 3-(acetyloxy)-11-oxo-, methyl ester, (3b)- is a complex organic compound with the chemical formula C32H50O5. It is a derivative of urs-12-en-28-oic acid, characterized by the presence of an acetyloxy group at the 3-position and an 11-oxo group. The compound is a methyl ester, indicating that a methyl group has replaced the hydroxyl group of the parent acid. This specific stereochemistry at the 3-position is denoted as (3b)-, which refers to the orientation of the hydroxyl group in the molecule. It is a naturally occurring substance found in plants and has potential applications in pharmaceuticals and cosmetics due to its biological activities.

22425-72-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22425-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22425-72:
(7*2)+(6*2)+(5*4)+(4*2)+(3*5)+(2*7)+(1*2)=85
85 % 10 = 5
So 22425-72-5 is a valid CAS Registry Number.

PROLONGED TREATMENT OF ACETYLMETHYL URSOLIC ACID WITH H2O2/ACETIC ACID - A FACILE ONE-POT SYNTHESIS OF 15α-HYDROXY ANALOGUE

, p. 3569 - 3580 (2007/10/02)

With a view to obtain new compounds bearing potential applications in the biogenetic type synthesis of natural products, acetylmethyl ursolic acid (1) was subjected to prolonged treatment with H2O2/AcOH on boiling water bath.Several such products (2, 3, 5 and 7) have thus been obtained.A new one-pot partial synthesis of 15α-hydroxy Δ12-analogues of pentacyclic triterpenes of amyrin series has been achieved. 13C-NMR spectral data of the major product are also described.
