Methyl 2-nonenoate brings out the subtle characteristics of watermelon, while methyl 3-nonenoate enhances the more cartoonish watermelon notes.

Methyl 2-nonenoate appeared on flavorists’ shelves first and was a vast improvement on the traditional methyl 2-octynoate and methyl 2-nonynoate, giving a much more natural effect in flavors. Methyl 3-nonenoate arrived quite a few years later. At first glance, both chemicals had a similar dominant melon green note, but, in practical use, they displayed significant differences.

Note that the dose rates given throughout this article are the levels suggested for use in flavors intended to be dosed at 0.05% in ready-to-drink beverages or in a simple bouillon.
