  • Applications

    5-Ethenyltetrahydro-beta,5-dimethyl-alpha-(3-methyl-2-butenyl)-2-furanethanol (CAS 20482-12-6) is a lipophilic, volatile terpenoid-like furan alcohol that is being explored and can be employed as: (1) a fragrance modifier for fine fragrances, personal care, and air‑care, imparting warm woody, resinous, herbal, subtly fruity facets and serving as an intermediate for pro‑fragrance esters/ethers to enhance substantivity; (2) a trace/low‑dose flavor contributor reinforcing roasted‑caramel and spicy furan tones in formulated foods, with any use subject to safety assessments and local regulations; (3) a synthetic building block, since its allylic alcohol with isoprenyl/vinyl handles enables esterification, etherification, carbonate formation, epoxidation and furan‑ring transformations to expand terpenoid libraries for pharma and agro lead discovery; (4) an analytical reference/marker in GC‑MS or LC‑MS profiling of essential oils, resins and authenticity checks, and for stability testing under light/heat/oxidation; (5) a candidate for preclinical bioactivity screens (antimicrobial, antifungal, antioxidant, insect attraction/repellency) to generate hypotheses, and a payload suitable for microencapsulation or inclusion complexes (e.g., cyclodextrins) to control scent release or polymer anchoring for slow‑release systems; all applications require case‑by‑case evaluation of toxicology, flammability, and matrix compatibility.
