Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in cross-coupling reactions such as Sonogashira coupling. Its silyl-protected alkyne group allows for selective and efficient transformation into bioactive molecules. Commonly employed in the development of kinase inhibitors and other nitrogen-containing heterocyclic compounds in medicinal chemistry. Also utilized in materials science for constructing conjugated systems in organic electronics due to its stable alkyne functionality and aromatic amine group.
