Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Sonogashira coupling reactions to introduce pyridine-based frameworks. Its silyl-protected alkyne group allows for selective deprotection and further functionalization, making it valuable in the development of conjugated materials for optoelectronics and organic semiconductors. Also employed in the synthesis of ligands for catalysis and in medicinal chemistry for constructing nitrogen-containing heterocyclic systems.
