This ester finds some use in perfume compositions, especially in herbaceous fragrances, where a warm, mild background note is desirable, e.g. in Lavender-Chypres, along with Oakmoss and Opopanax, etc. but also under distinctly floral fragrances, as a 'natural' mellow note in Lily, Rose, etc. It performs very well as a companion to Coriander in modern 'fantasy' type fragrances.
Produced by direct esterification of n-Decanol with 2-Butenoic acid (trans-Crotonic acid).
