Used in organic synthesis as a reagent for cross-coupling reactions, particularly Stille coupling, for the formation of carbon-carbon bonds. It is valuable in the preparation of complex organic molecules, including pharmaceuticals and agrochemicals. The compound serves as an organostannane coupling partner, enabling the introduction of the 8-quinolinyl group into target molecules. It is also employed in the development of advanced materials, such as organic semiconductors and light-emitting diodes (LEDs), due to its ability to modify electronic properties. Additionally, it finds use in research for studying organometallic chemistry and catalytic processes.
