Usage

General Description

S-Ethyl thiopropionate is an organic compound with the chemical formula C5H10OS. It is a colorless liquid with a strong odor, commonly used in the food and beverage industry for its fruity and sweet aroma, resembling that of pineapple. It is also utilized in the production of fragrances and as a flavoring agent. S-Ethyl thiopropionate is classified as a potentially hazardous substance, as it can cause irritation to the skin, eyes, and respiratory system upon contact or inhalation. Therefore, proper safety precautions should be observed when handling this chemical.

Investigations of the Thermal Responsiveness of 1,4,2-Oxathiazoles

The first systematic study of the thermal rearrangement/fragmentation of 5,5-disubstituted 1,4,2-oxathiazoles into isothiocyanates is reported. Structure-activity relationships reveal that the choice of substituent at the 5-position of the 1,4,2-oxathiazoles is the predominant factor to influence the ease of fragmentation.

Zinc promoted convenient and general synthesis of thiol esters

Synthesis of thiol esters from acyl chlorides and thiols in the presence of activated zinc is described. The recovery of zinc and its reuse makes the procedure more economic.

Acid-Catalyzed Hydrolysis of Ketene Dithioacetals and Trithioorthocarboxylates. Effect of β-Methyl Substitution

Hydrolysis rates of β-methyl-substituted ketene dithioacetals were measured. β-Monomethyl and β,β-dimethyl substitutions reduced the reactivity of the parent acetal by factors of 26 and 6.7 x 105, respectively.Similar methyl substitutions of trithioorthoacetate, however, enhanced the hydrolysis reactivity by 3 and 23 times.The reversibility of protonation of ketene dithioacetal during hydrolysis was slightly increased by a β-methyl group, but dimethyl substitution seemed to inhibit reversibility by raising the potential barrier to protonation.
