  • Applications

    3-Propylidene-2-heptanone (CAS 32064-70-3) is used primarily as an intermediate in the synthesis of specialty fragrance compounds and odorants for perfumery, and may serve as a fragrance ingredient in cosmetics and personal-care products; it is also evaluated for applications in flavor/aroma formulations. In industrial manufacturing, it acts as a building block for related ketones and other specialty chemicals, including polymer and plastic resin precursors. Additionally, it is explored as a processing aid or chemical intermediate in coatings, inks, and adhesives formulations, where its ketone functionality participates in formulation chemistry. Use is subject to local regulations and formulation limits.
