Not confined to the Chamomile type of herbaceous notes, DI-N-hexyl fumarate can supply fixation of the herbaceous notes in Lavender, Geranium, Lavandin, Rosemary, Clary sage, etc. and it blends well into Fougeres, Chypres, Oriental types, etc.
DI-N-hexyl fumarate has the advantage of being much less expensive than the TigIic and Angelic esters, and since Fumaric acid is commercially available in high grade of purity, it also offers an ester free from isomers (until recently, Tiglic acid was not available at reasonable cost unless accompanied by a considerable amount of Angelic acid).

DI-N-hexyl fumarate can be produced by direct esterification of n-Hexanol with Fumaric acid under azeotropic conditions.
