  • Applications

    Methyl 2,4-decadienoate, (2E,4E)- (CAS 7328-33-8) is a conjugated dienoate ester with a green, fruity pear–apple–pineapple, slightly waxy odor, used at very low levels as a flavor and fragrance ingredient in foods, beverages, confectionery, baked goods and chewing gum to deliver crisp top notes and prolong aftertaste, and in fine fragrances, personal care and household perfumery to boost bright top accords, blending well with lactones, terpene esters and aldehydes; in agriculture and chemical ecology it is employed as a structural analog/mixture component alongside other 2,4-decadienoate esters for screening insect lures and as a reference standard in olfactory response studies and trap optimization (the ethyl analog is more widely deployed); in analysis it serves as a GC–MS/LC–MS calibration/retention standard and QC spike for qualitative and quantitative methods on dienoates; and in organic synthesis it functions as a C10 building block for addition, hydrogenation/isomerization and olefin metathesis routes to related derivatives; all uses should follow safety and regulatory guidance, with storage tightly sealed and protected from light/oxygen to minimize isomerization and oxidation.
