  • Applications

    Hex-1-en-1-yl butanoate (CAS 26912-31-2) is a flavor and fragrance ester with fresh fruity–green character, widely used to build and lift apple, pear, and tropical nuances, brighten top notes, and enhance juiciness in beverages, confectionery, baked goods, and dairy analogs; in perfumes, personal care, and home care it imparts a natural “fresh-cut” green freshness, rounds citrus facets, and modulates fruit accords in combination with acetates, lactones, and other butyrates; it also serves in R&D as a reference/standard for GC/MS method development, aroma-release (encapsulation, microcapsules) studies, stability testing, and accord building, and as an organic synthesis intermediate for related esters; formulators should assess compatibility (typical ester sensitivity to hydrolysis/oxidation), manage storage/packaging, and comply with safety guidelines, local regulations, and industry practices.
