(-)-(1R,2S)-2-heptylcyclopropanecarboxylic acid - The enantiomers of the cis isomer give odour notes that can be described as follows: woody, balsamic, incense-like, green, herbal, pith-like and waxy; In addition, mixtures of the enantiomers of the cis isomers of 2-heptylcyclopropyl-1-carboxylic acid have a balsamic, peel-like but not aldehydic flavour note. However, the non-natural (1R,2S) cis enantiomer displays a very much weaker odour than the naturally occurring (1S,2R) enantiomer.

However, the natural (1S,2R) cis enantiomer displays a very much stronger odour than the non-naturally occurring (1R,2S) enantiomer. The odour threshold for the racemic mixture of cis-2-heptylcyclopropyl-1-carboxylic acid is 3 ppb in water and is thus extremely low.
