  • Applications

    As (2Z,6E)-2,6-Nonadienal, it is used primarily as an aroma/odorant in fragrance and personal care products, contributing green, cucumber-like or fresh notes in perfumes and cosmetics. It may be employed as a flavor/aroma ingredient in food processing where permitted by regulation. It can serve as an odorant in household and cleaning products to impart a fresh, green note. In industrial manufacturing, it is often used as an intermediate or building block in the synthesis of other fragrance compounds, enabling formulation development for scent profiles.
