Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its trifluoromethanesulfonate group makes it a valuable reagent for introducing functional groups or constructing complex molecular structures. Often employed in cross-coupling reactions to create carbon-carbon or carbon-heteroatom bonds, which are essential in drug discovery and material science. Additionally, its cyclopenta[b]pyridine core is a key building block for compounds with potential biological activity, such as enzyme inhibitors or receptor modulators.
