(3R)-(-)-3-mercaptoheptyl acetate - 3-mercaptoheptyl acetate (as the racemate) possesses a relatively weak top note reminding of a peach, citrus and tea tonality. This top note is followed by highly appreciated and performing bottom notes of the green/black tea type as well as of the citrus-grapefruit and fruity-pear-peach type which render said compound a very useful flavoring ingredient.

(3S)-(+)-3-mercaptoheptyl acetate - The two enantiomers of the cited acetate, namely the (R) and the (S) ones, are also valuable flavoring ingredients, which can be used in a similar way. Amongst said enantiomers the most appreciated is the (S) one, which has a taste very close to the one of the racemate, although its grapefruit type note is weaker than the one of the racemate.
