5-Chloro-6-methoxy-1-indanone is a substituted indanone derivative serving as a key intermediate in pharmaceutical synthesis. It is particularly used in the development of bioactive compounds with indane-based structures, such as those targeting central nervous system disorders or exhibiting antioxidant properties. This compound facilitates the construction of complex heterocyclic molecules and is commonly employed in research laboratories to synthesize novel derivatives for structure-activity relationship studies.
