(3R)-(-)-3-mercaptoheptyl acetate - Escher et al. indicate that 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. Liang et al. describe the racemate as sulfurous, sweet, fruity (on a smelling strip).  Ref: Sina Dorothea Escher, Yvan Niclass Lionel Saudan, Thiols as Flavouring Agents, PCT WO2006120625 (November 16, 2006); Sen Liang, Baoguo Sun, Shaoxiang Yang, Yongguo Liu, Hongyu Tian, Yuping Liu, and Haitao Chen.

(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. Liang et al. describe (3S)-(+)-3-mercaptoheptyl acetate as follows - The odour properties were evaluated by chiral GC-O. It possessed a tropical fruit aroma reminiscent of mango and passion fruit, with berry, ester-like, sweet, and pepper-like aspects.  Ref: Sina Dorothea Escher, Yvan Niclass Lionel Saudan, Thiols as Flavouring Agents, PCT WO2006120625 (November 16, 2006); Sen Liang, Baoguo Sun, Shaoxiang Yang, Yongguo Liu, Hongyu Tian, Yuping Liu, and Haitao Chen.
