  • Applications

    Benzylidene dimethoxydimethylindanone (CAS 924626-15-3) is primarily used as an organic-synthesis intermediate. In fragrance chemistry it may function as an odorant or fragrance precursor, contributing to specialty perfumery formulations. In cosmetics and personal care it can serve as a formulation intermediate or building block for aroma-related additives. In polymers and plastics it may act as a precursor for specialty monomers or additives used to modify material properties. In coatings and inks it can be used as an aromatic ketone intermediate for the formulation of specialty coatings. In pharmaceutical development it may be evaluated as a synthetic intermediate, subject to local regulations and formulation limits.
