  • Applications

    1-[(1S)-3alpha-Methyl-2alpha-(3-isopropylfuran-2-yl)cyclopentan-1alpha-yl]ethanone (CAS 1143-46-0) is a stereodefined cyclic ketone used in aroma and fine-organic-chemistry research: as an analytical reference for GC-MS/LC-MS and for developing chiral separation methods, to probe structure-odor relationships of furan-cyclopentanone systems (explored for amber/woody, jasmonoid-like notes), as a synthetic intermediate to access related isoprenoid/cyclopentanoid scaffolds, as a reference in stability/oxidation and formulation-compatibility studies, and as a model compound for SAR screening in pharma/agro discovery; it is typically supplied for research-use-only and testing purposes, not for direct use in foods or therapeutics unless appropriate approvals are obtained.
