Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals, particularly in cross-coupling reactions due to the presence of the ethynyl group protected by trimethylsilyl. The amine functionality allows for further derivatization, making it valuable in the construction of nitrogen-containing heterocycles. Commonly employed in Sonogashira coupling reactions to form conjugated systems for materials science applications, including organic semiconductors and fluorescent probes. Its silyl-protected alkyne offers stability during reactions, with the option to deprotect and extend molecular structure when needed.
