625-60-5 Usage
Description
Ethanethioic acid S-ethyl ester, also known as Ethyl thioacetate, is a volatile sulfur compound characterized by its alliaceous, coffee odor. It is a colorless liquid with a sulfuraceous, onion-garlic taste at 10 ppm, accompanied by a sweet, fruity aftertaste. Ethanethioic acid S-ethyl ester is naturally found in various sources, including beer, white wine, red wine, rose wine, durian (Durio zibethinus), and coffee.
Uses
Used in Flavor Industry:
Ethanethioic acid S-ethyl ester is used as a flavoring agent for its unique sulfuraceous, onion-garlic taste with a sweet, fruity aftertaste. It adds a distinct flavor profile to the products in which it is used.
Used in Wine Production:
In the wine industry, ethyl thioacetate is used to enhance the aroma and taste of various types of wine, such as white, red, and rose wine. Its presence contributes to the complex flavor profile of these beverages.
Used in Coffee Production:
Ethanethioic acid S-ethyl ester is also used in the coffee industry to impart its characteristic coffee odor and flavor to the final product, enhancing the overall sensory experience of coffee consumption.
Used in Durian Production:
Ethanethioic acid S-ethyl ester is utilized in the durian industry to add its distinct sulfuraceous, onion-garlic taste with a sweet, fruity aftertaste to the durian fruit, making it more appealing to consumers.
Preparation
From acetyl chloride and ethyl mercaptan.
Check Digit Verification of cas no
The CAS Registry Mumber 625-60-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 625-60:
(5*6)+(4*2)+(3*5)+(2*6)+(1*0)=65
65 % 10 = 5
So 625-60-5 is a valid CAS Registry Number.

Silver triflate catalyzed acetylation of alcohols, thiols, phenols, and amines
Das, Rima,Chakraborty, Debashis
experimental part, p. 1621 - 1625 (2011/06/25)
A variety of alcohols, thiols, phenols, and amines were subjected to acetylation reaction using acetic anhydride in the presence of catalytic quantity of silver triflate. The method described has a wide range of applications, proceeds under mild conditions, does not involve cumbersome workup, and the resulting products are obtained in high yields within a reasonable time.

Facile catalyzed acylation of heteroatoms using BiCl3 generated in situ from the procatalyst BiOCl and acetyl chloride
Ghosh, Rina,Maiti, Swarupananda,Chakraborty, Arijit
, p. 6775 - 6778 (2007/10/03)
Acylation of a variety of alcohols, phenols, aliphatic and aromatic amines, a thiol and a thiophenol proceeds efficiently using BiCl3 generated in situ from the procatalyst BiOCl and acetyl chloride in a solvent or under solventless conditions, furnishing the corresponding acylated derivatives in very good to excellent yields.
