Methyl 2-nonynoate has a characteristic violet-like odor with a sweet taste reminiscent of fresh peach, unripe banana, and cucumber peel. May be prepared from 2-octene by way of 1-octyne and octyne carboxylic acid.

Both methyl 2- nonynoate and methyl 2-octynoate have a triple bond and are liquids with a fatty, violet-leaf-like odor.They are used in perfume compositions.

METHYL 2-NONYNOATE is used as ester-based synthetic flavorings, as specified in GB 2760-1996, are permitted food flavorings, primarily used in the formulation of flavorings such as green banana, cucumber, peach, lychee, longan, and melon. They possess a green floral aroma and can be combined with other flavorings in flavorings such as gardenia, tuberose, violet, osmanthus, and rose. They are also used in acacia compound, orchid, and other formulations containing ionones to enhance aroma and provide top notes. In trace amounts, they are used in food flavorings to imitate the aromas of peach, banana, lychee, longan, cucumber, melon, currant, and berry flavors.

ChEBI: Methyl non-2-ynoate is a ynoate ester.

From 2-octene by way of 1-octyne and octyne carboxylic acid.
