  • Applications

    Cis-2-(2-Pentenyl)furan (CAS 70424-13-4) is primarily used as a flavor ingredient, contributing green, fruity, roasted-nut and light caramel nuances that enhance freshness and depth in foods and beverages such as coffee, tea, baked goods, cereals, snacks, and alcoholic drinks; in fine fragrance and home care it serves as a mid-note “bridge” between green and warm-roasted facets, adding complexity to accords; in aroma–flavor research it is employed as a reference standard for sensory/GC–MS work and Maillard-model studies; additionally, in organic and agro/pharma chemistry the furan core acts as a versatile scaffold while the cis-pentenyl chain enables regio-/stereoselective additions, oxidations, or couplings to access new aroma ingredients, technical odorants, and functional scented materials.
