  • Applications

    Decahydro-2,2,7,7,8,9,9-heptamethylindeno(4,3a-b)furan, CAS 647828-16-8, is primarily used as a rigid hydrocarbon building block in organic synthesis and can serve as a specialty intermediate for the preparation of complex chemicals; it is sometimes employed as a fragrance intermediate or fixative in perfumery; in materials science, it may function as a hydrophobic, rigid scaffold for high-performance polymers and as an additive in coatings and inks; it is also of interest as a scaffold for electronic or optoelectronic material research within industrial settings, subject to regulatory controls and formulation limits.
