Linalool je prirodni terpenski alkohol koji je prisutan u mnogim cvetajućim i začinskim biljkama. On ima mnoštvo komercijalnih primena, većina kojih se bazira na prijatnom mirisu. Njegova druga imena su: β-linalool, linalil alkohol, linaloil oksid, p-linalool, alo-ocimenol, i 2,6-dimetil-2,7-oktadien-6-ol.

Priroda

Preko 200 biljnih vrsta proizvodi linalool. One su uglavnom iz porodica Lamiaceae (menta, mirišljave trave), Lauraceae (lavor, cimet, palisandrovo drvo), i Rutaceae (citrusno voće).

Enantiomeri

Linalool ima stereogeni centar na C3 i stoga postoje dva stereoizomera: (R)-(–)-linalool je takođe poznat kao likareol i (S)-(+)-linalool ili koriandrol.

(S)-(+)-linalool (levo) i (R)-(–)-linalool (desno)
