2,6-dimethyl-2,18-nonadecadien-8-one

2,6-dimethyl-2,18-nonadecadien-8-one belongs to the class of long-chain ketones characterized by a molecular structure featuring methyl substitutions at the 2 and 6 positions and unsaturation at the 2 and 18 carbon atoms. It exhibits a complex organoleptic profile comprised of aldehydic, musky, woody, floral, fruity, minty, and clean odor notes when dissolved in dipropylene glycol at 10%. This compound is recognized under multiple synonymous names with consistent molecular identity and is referenced in chemical databases such as PubChem for structural and physical data. Typically sourced through synthetic organic methods, 2,6-dimethyl-2,18-nonadecadien-8-one is primarily employed for informational and research purposes and has no commercial presence in fragrance or flavor formulations.

This compound does not naturally occur in significant quantities in the biological environment but represents a synthetic entity studied for its distinctive odor profile. Its application is confined to research contexts rather than industrial fragrance or flavor use, which is explicitly restricted by safety guidelines. The compound's assessment with respect to standards such as REACH (EU) focuses on regulatory compliance for chemical substances without endorsement for perfumery or food flavoring. Potential uses beyond olfactory research remain limited, making it a subject of interest primarily in chemical characterization and safety information repositories.

2,6-dimethyl-2,18-nonadecadien-8-one demonstrates solubility in alcohol but is insoluble in water, indicating a largely hydrophobic nature reinforced by its extended hydrocarbon chain and unsaturated sites. These solubility traits affect formulation design, limiting compatibility with aqueous-based systems and favoring organic solvent matrices. The molecular structure, featuring multiple double bonds and methyl branching, imparts a distinctive odor and influences volatility and stability profiles relevant for sensory or analytical purposes. Its physicochemical characteristics underscore its role as a specialized compound in odor research rather than routine application in fragrance or flavor products.
