  • Applications

    Isojasmone (CAS 11050-62-7) is primarily used as a jasmine-like fragrance ingredient in perfumery, providing distinctive floral notes. Real-world applications include perfumes and cosmetics/personal care, as well as household products such as air fresheners and cleaners, where it serves as a fragrance ingredient. It may also function as an intermediate in fragrance synthesis or as a fragrance additive in polymer materials to impart aroma, depending on regulatory requirements and formulation limits.
