  • Applications

    11-Hydroxy-10-methyl-7-propan-2-yl-2-oxatricyclo[6.3.1.04,12]dodeca-1(12),3-dien-5-one (CAS 5956-13-8) is a specialized oxygen-containing tricyclic compound bearing hydroxy and ketone functionalities. In practice, its applications are typically as an intermediate or building block in organic synthesis for pharmaceutical and agrochemical development. It is also considered as a fragrance ingredient or fragrance intermediate for perfumery, with potential niche use in cosmetics/personal care as a specialty aroma component. Owing to its ring framework and oxygen-containing functionality, it can serve as a starting point for the synthesis of terpene-derived materials and related derivatives, and may be employed in process development and analytical method studies.
