  • Applications

    Decanone (unknown isomer, CAS 29221-56-5) is a C10 aliphatic ketone valued for solvency and a characteristic odor; in practice, decanone isomers are used as slow-evaporating solvents for coatings, inks, adhesives and sealants to dissolve resins and tune dry time and flow; as carriers/co-solvents in industrial and household cleaners, polishes, deodorizers and personal care; as intermediates to make surfactants, fragrance esters and other fine chemicals; as fragrance ingredients and, where permitted, flavor notes, with different isomers contributing fatty, waxy, fruity or citrus-green nuances and acting as fixatives; as solvents or carriers in agrochemical formulations and wood preservatives; and in R&D as working standards or reference solvents when studying odor, polymer compatibility or kinetics of long-chain ketones; note that certain repellent uses are known for 2-decanone (methyl nonyl ketone), but efficacy, odor profile, volatility and regulatory status depend on isomer and purity, so the specific isomer, safety specifications and local compliance should be confirmed before selecting an application.
