3-Oxothiobutyric acid S-ethyl ester, also known as ethyl 3-oxothiobutanoate or ethyl 3-ketobutyrate, is an organic compound with the chemical formula C6H10O2S. It is a colorless liquid with a fruity, apple-like odor. This ester is formed by the reaction of ethyl alcohol and 3-oxothiobutyric acid, and it is used as a synthetic flavoring agent in the food and beverage industry, particularly in the production of apple and pear flavors. It is also employed in the fragrance industry for creating fruity and floral scents. Due to its relatively low toxicity, it is considered safe for use in these applications.

3075-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3075-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,7 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3075-23:
(6*3)+(5*0)+(4*7)+(3*5)+(2*2)+(1*3)=68
68 % 10 = 8
So 3075-23-8 is a valid CAS Registry Number.

Acylations of Thiol Ester Enolate Anions

Wilson, G. Edwin,Hess, Arye

, p. 2766 - 2772 (2007/10/02)

The synthetic utility of thiol ester anions has been explored.Claisen condensations of thiol esters with isopropylmagnesium bromide base proceed in good yield.The Dieckmann reaction of diethyl thiolpimelate to form a six-membered ring proceeds in 74 percent yield, but the corresponding reaction of diethyl thioladipate to provide a five-membered ring gives only 26 percent yield.Neither alkylation of ethyl thiolacetate nor a Michael-type adduct with methyl vinyl ketone could be achieved.The mechanism of the Claisen condensation as it applies to thiol esters is discussed.
