This ester is primarily used in flavor compositions, since it is more fruity than the cis-3-Hexenyl acetate, and less sharp-green. Among the few places in perfumery where it may find good use are certain artificial essentia] oils such as Geranium, Clary Sage, Ylang-Ylang, etc.
The ester is used in various fruit imitation flavors in minute traces, so that the concentration in the finished products is rarely more than 0.3 to 2 ppm. Banana, Apple, Pear, Melon, etc. are among the many types where this ester can be useful.
Produced by esterification of trans-2-Hexenol with Acetic acid under azeotropic conditions.
