(3R)-Butylphthalide - Herbaceous, celery-like odor; typical for the odor of celery and celeriac This enantiomer shows a significantly higher (>100 X) GC odour threshold value than does the (3S)-enantiomer.

(3S)-Butylphthalide - Herbaceous, celery-like odor; This enantiomer shows a significantly lower (>100 X) GC odour threshold value than does the (3R)-enantiomer. Odor Threshold = 0.01 ng Mosandl's investigation of the essential oil of celery seed show enantiomeric distributions in the range of 95:5 in favour of the (3S)-enantiomer Ref: Dietmar Bartschat, Birgit Maas, Sabine Smietana, Armin Mosandl, Stereoisomeric Flavour Compounds LXXIII: 3-Butylphthalide: Chirospecific Analysis, Structure and Properties of the Enantiomers, Phytochemical Analysis, 7(3), 131-135 (1996); Odor description from Leffingwell, Flavor-Base 2001
