TCI H0569 2-Heptylcyclopentanone is a five-membered cyclic ketone carrying a long heptyl chain at the alpha position relative to the carbonyl group. This structural motif is the characteristic skeleton found among jasmine-type aroma compounds, which is why the material is widely used both as a building block and as a reference compound in flavor and fragrance research. In the laboratory, this compound helps researchers understand the relationship between side-chain length, carbonyl group position, and the aroma character produced by a substituted cyclopentanone molecule.
The characteristic that makes it a preferred choice is the presence of an active alpha position adjacent to the carbonyl, so the compound readily undergoes deprotonation and further reaction through alkylation, aldol, or condensation pathways to form cyclopentenone derivatives. Its five-membered ring provides conformational rigidity that helps direct the stereochemistry of reactions, while the heptyl chain confers high lipophilicity and good solubility in nonpolar organic solvents. This combination yields a material that is stable under normal storage, easy to extract, and gives clear spectroscopic signals for structural tracing.
In Indonesian laboratories, this material is typically handled in university research groups, flavor and fragrance development units, and synthetic chemistry laboratories that build non-heterocyclic frameworks. It is commonly used in small-scale preparative work, as a reference standard for chromatographic and spectroscopic identification, and in method development where a well-defined substituted cyclopentanone is needed as a starting point or comparison compound.

Store the container tightly closed in a cool, dry, and well-ventilated area, away from heat sources, open flame, and direct sunlight. Keep the material in its original manufacturer packaging or in a compatible chemically resistant container, and keep it separated from strong oxidizing agents and strong bases that may react with the carbonyl group or the active alpha position. Handle inside a fume hood while wearing safety goggles, gloves, and a laboratory coat. Because the compound is lipophilic and easily extracted into organic solvents, avoid skin contact and clean spills promptly with appropriate absorbent material. Always consult the manufacturer's safety data sheet before use.
