Used as a key intermediate in palladium-catalyzed cross-coupling reactions, particularly in the synthesis of complex organic molecules for pharmaceuticals and agrochemicals. Its triflate group is highly reactive toward nucleophiles, enabling efficient carbon-carbon bond formation. The trimethylsilyl group can be selectively removed or transformed, allowing further functionalization. Commonly employed in the preparation of substituted pyridines, which are important structural motifs in drug discovery and materials science.
