  • Applications

    5‑Dodecenal (5E) (CAS 68820‑34‑8) is an unsaturated C12 aliphatic aldehyde used broadly as a fragrance and flavor ingredient, imparting citrus, green, fatty‑waxy aldehydic nuances that enhance freshness and diffusion in fine fragrances, personal‑care formulations, and home‑care scents, while modulating citrus and fruity flavor profiles at trace levels; in research and manufacturing it also serves as a versatile organic building block for preparing derived molecules, as an analytical reference standard for chromatographic determination of long‑chain aldehydes and lipid‑oxidation products, and as a semiochemical component in entomological lures for insect monitoring.
