Description
TCI G0236 Geranylacetone is an open-chain terpenoid ketone belonging to the acyclic sesquiterpenoid class, occurring naturally as a volatile compound in a wide range of plants, fruits, and flowers. The product is supplied as a mixture of the geometric (E)- and (Z)-isomers in a ratio of approximately 3:2. In the laboratory, geranylacetone serves two important roles at once: as a synthetic intermediate in routes toward isophytol and vitamin E, and as a marker compound in aroma research, natural product chemistry, and studies of chemical communication between plants and insects.
The characteristic that makes this material a preferred choice is the combination of a reactive ketone group with two isoprenoid double bonds on the same carbon skeleton. Its carbonyl group is ready to undergo addition reactions, aldol condensation, and chain extension, while its double bonds allow epoxidation, cyclization, and selective hydrogenation. Physically the compound is a colourless to pale yellow liquid with a soft floral-green odour, soluble in organic solvents and practically insoluble in water. The liquid form makes volumetric transfer by micropipette or syringe straightforward, with no need for prior dissolution.
Indonesian laboratories typically use this compound in organic synthesis groups, natural product and flavour-fragrance research units, and analytical facilities that require a reference substance for aroma and volatile compound work. Because it is handled as a ready-to-use liquid, it fits routine workflows in university research laboratories, institutional chemistry laboratories, and industrial research and development settings that study terpenoid chemistry or plant-insect chemical interactions.
Laboratory Applications
- Synthetic intermediate preparation: the reactive carbonyl group and isoprenoid double bonds allow geranylacetone to be carried forward along established routes toward isophytol and vitamin E.
- Aroma and fragrance research: its soft floral-green odour and natural occurrence in plants, fruits, and flowers make it a relevant marker compound for volatile profiling studies.
- Natural product chemistry studies: as a naturally occurring acyclic sesquiterpenoid, it supports investigations of terpenoid biosynthesis, structure, and reactivity within research programmes.
- Plant-insect chemical communication research: geranylacetone functions as a marker compound in studies examining how volatile signals mediate interactions between plants and insect species.
- Carbonyl and alkene transformation work: the same molecule supports addition, aldol condensation, chain extension, epoxidation, cyclization, and selective hydrogenation experiments in methodology development.

Handling and Storage
Store the container tightly closed in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and ignition sources. Amber glass bottles or the original manufacturer packaging are suitable, since the material is a light-sensitive organic liquid; avoid transferring it into containers made from incompatible plastics. Handle inside a fume hood and wear standard laboratory personal protective equipment, including safety glasses, gloves, and a laboratory coat. Because the compound is volatile and carries a noticeable odour, keep the bottle closed when not in active use, withdraw portions with a clean syringe or micropipette to prevent contamination, and record the date of first opening. Dispose of residues and contaminated materials in accordance with the applicable chemical waste procedures of your institution.
