Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactivity makes it suitable for introducing the 1-(4-chlorophenyl)cyclopentane moiety into larger molecules, particularly in the development of bioactive compounds. Commonly employed in amidation and esterification reactions due to the presence of the acid chloride group, enabling the formation of amides or esters under mild conditions. Frequently utilized in research settings for the preparation of analogs in structure-activity relationship (SAR) studies. Its chlorinated aromatic and alicyclic structure contributes to enhanced lipophilicity, which can improve membrane permeability in drug candidates.
