  • Applications

    3-Methylnonanal (CAS number: 65899-13-0) is primarily used as an odorant and fragrance ingredient in perfumery and cosmetics, and is commonly included in household products such as air fresheners and cleaners to impart distinctive notes. It also functions as a chemical intermediate, providing a building block for the synthesis of other aroma compounds and for specialty intermediates used in industrial manufacturing. In the polymers/plastics sector, it may be used as a precursor for fragrance-related additives or as a reactive intermediate in formulation workflows. In coatings and inks, it can contribute as a fragrance component or as a precursor in fragrance-related additive systems. Its use is formulation-dependent and subject to local regulations.
