Benzoic acid-(3-methoxy-estratrien-(A)-yl-(17β)-ester) is a complex organic compound that belongs to the class of steroidal esters. It is derived from the combination of benzoic acid and a specific type of estratrien, which is a class of steroidal compounds. This particular ester is characterized by the presence of a 3-methoxy group and a 17β-ester functional group, which are key to its chemical structure and properties. The compound is of interest in the field of pharmaceuticals and endocrinology due to its potential applications in hormone therapy and as a research tool for understanding steroidal mechanisms. Its chemical structure provides a basis for its interaction with biological systems, particularly in relation to estrogen receptors.

4828-26-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4828-26-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4828-26:
(6*4)+(5*8)+(4*2)+(3*8)+(2*2)+(1*6)=106
106 % 10 = 6
So 4828-26-6 is a valid CAS Registry Number.

Benzyne-Mediated Esterification Reaction

Li, Yang,Shi, Jiarong,Zhao, Jinlong

supporting information, p. 7274 - 7278 (2021/10/01)

A benzyne-mediated esterification of carboxylic acids and alcohols under mild conditions has been realized, which is made possible via a selective nucleophilic addition of carboxylic acid to benzyne in the presence of alcohol. After a subsequent transesterification with alcohol, the corresponding esters can be produced efficiently. This benzyne-mediated protocol can be used on the modification of Ibuprofen, cholesterol, estradiol, and synthesis of nandrolone phenylpropionate. In addition, benzyne can also be used to promote lactonization and amidation reaction.

Benzoyl Trifluoromethanesulfonate. A Mild Reagent for the Benzoylation of Sterically Hindered Hydroxyls

Brown, Lindsey,Koreeda, Masato

, p. 3875 - 3880 (2007/10/02)

Benzoyl trifluoromethanesulfonate (BzOTf) is a highly efficient reagent for the benzoylation of a variety of alcohols under mild conditions.These include hindered secondary and tertiary hydroxyls, phenols, and α-glycols.Sensitive functionality is stable when the reaction is performed in the presence of pyridine.Several unique rearrangements of Lewis acidsensitive compounds were also effected.
