  • Applications

    Jasmolactone (CAS 32764-98-0) is a fragrant lactone with a delicate jasmine-like, fruity odor used extensively in the aroma industry—from high-end perfumes and cosmetic fragrances to soaps, shampoos, and personal-care products—where it imparts depth, gentle sweetness, and a natural white-floral nuance; in food technology it is incorporated at trace levels as a flavoring for confectionery, beverages, and plant-based dairy alternatives to recreate tropical-fruit notes and round out formulations; in tobacco flavorings, scented candles, and diffuser oils it softens harshness and enhances a relaxing impression; moreover, owing to its compatibility with many aldehydes and ketones, Jasmolactone is valued by perfumers and flavor chemists as a versatile building block for next-generation accords, aligning with the industry’s “green & natural” trend and supporting a more sustainable global fragrance supply chain.
