  • Applications

    Indan (CAS 496-11-7) is a bicyclic hydrocarbon that is primarily used as an organic synthesis intermediate and a building block for a range of commercial compounds. In practice, it is evaluated as a precursor for fragrance and flavor-related intermediates and cosmetic/fragrance ingredients; used as a starting material for pharmaceutical intermediates; employed as a precursor for specialty polymers and plastics; applied in coatings and inks as a synthesis feedstock or foundational precursor; and may be considered for other industrial synthesis applications depending on process routes and local regulations.
