Cassyrane (IUPAC Name: 2-tert-butyl-5-methyl-2-propyl-2,5-dihydrofuran) is a patented, high-impact synthetic fragrance ingredient developed by the Swiss flavors and fragrances manufacturer Givaudan. Classified as an organoleptic aroma chemical, it is valued for its complex fruity-green profile and powerful performance in modern perfumery.

Cassyrane (CAS No.871465-49-5) belongs to the blackcurrant (cassis) olfactory family, though it exhibits a highly complex, multidimensional profile. In professional perfumery, its odor is described as:

Primary Notes: Blackcurrant (cassis), natural, rich, and intensely fruity.

Secondary Notes: Eucalyptus buds, anise, buchu leaves, and distinct herbal-green undertones.

Characteristics: It provides a highly natural, vibrant, and deep fruity quality that avoids the harsh, synthetic "sulfury" off-notes frequently associated with older blackcurrant-type aroma chemicals.

Uses and Flavor/Fragrance Applications

Cassyrane is a versatile ingredient used globally as a flavoring agent and fragrance modifier.

Fragrance Formulations

In fine fragrances and functional consumer products, Cassyrane functions as a top-to-middle note. Its intense performance allows perfumers to:

Introduce authentic, modern fruity notes into floral, citrus, and oriental accords.

Enhance "green" and herbal profiles, blending seamlessly with minty, camphoraceous, or aniseed ingredients.

Act as an olfactory booster to lift heavy base notes, adding brightness and diffusivity to a composition.

Flavor Formulations

Approved as a FEMA GRAS flavor chemical, Cassyrane is utilized in specialized food and beverage formulations. It contributes to:

Fruity flavor compositions, particularly blackcurrant, blackberry, and dark berry profiles.

Tropical and botanical flavor accents, lending depth to exotic fruit or herbal tea formulations.

Industrial & Commercial Applications

Because of its unique chemical architecture and stability, Cassyrane is widely incorporated across multiple industrial product sectors:

Fine Perfumery: Used in luxury eaux de parfum and eaux de toilette to impart high-impact, natural-acting blackcurrant dynamics.

Personal Care Products: Blended into shampoos, shower gels, and body lotions. It adds clean, crisp fruity-herbal notes that remain stable and clear when mixed with various surfactant bases.

Home Care/Detergents: Formulated into fabric softeners and liquid detergents. Its volatile structure ensures excellent diffusivity, elevating the initial burst of fragrance upon opening or during product use.
