Geranyl-linalool
chemical compound
Geranyl-linalool is a naturally occurring organic compound classified as a diterpenoid with the molecular formula C20H34O. This is a compound found in various plants and serves as an important intermediate in the biosynthesis of several biologically active compounds.
Chemical structure
Geranyl-linalool is classified as an acyclic alyphatic diterpenoid polyalkene alcohol. The compound includes four isoprene units arranged in a head-to-tail fashion, characteristic of diterpenes.
Natural occurrence
Geranyllinalool is found in various plant species, including: tobacco (Nicotiana tabacum) where it was first identified, ginkgo (Ginkgo biloba), various orchid species, some fungi and marine organisms. The compound is typically present in trace amounts and is often detected through careful phytochemical analysis.
Biosynthesis
Geranyl-linalool is biosynthesized via the plastidial MEP pathway. The compound is formed from geranylgeranyl diphosphate (GGPP) through the action of specific terpene syntheses. The compound serves as a precursor to various cyclic diterpenes and other biologically active compounds in plants. In tobacco, geranyl-linalool is part of the cembranoid diterpene pathway and can be further metabolized into various oxidation products.
Physcal properties
The compound forms a colorless to pale yellow liquid which is insoluble in water, but soluble in organic solvents.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Geranyl-linalool”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 2, 2026. The linked authority identifier is Q27144589. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
