3-Methyl-1-indanone is suitable for the synthesis of branched alkyl indanes (BINs).It may be used in the following studies:Synthesis of 2,2,3-tribromo-2,3-dihydro-3-methylinden-1-one and 2-bromo-3-bromomethyl-1H-inden-1-one.As photosensitizers for the splitting of dimethylthymine dimers.As a model to verify three-phase model in enantioselective gas-liquid chromatography.(-)-(R)-3-methyl-1-indanone may be used as standard for comparing the optical rotatory dispersion curve with 1,3-dialkylindenes in the study of base-catalyzed 1,3 proton transfer in indene systems.As an optically active sensitizer to induce asymmetry intrans-1,2-diphenylcylcopropane (DPC).The dl-isomers of 3-methyl-1-indanone may be used in the synthesis of monomeric and trimeric 3-methyl-1-indanethione.
