Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated materials for electronic applications. It serves in the fabrication of organic semiconductors, OLEDs (organic light-emitting diodes), and molecular wires due to its ability to undergo Sonogashira coupling reactions. The trimethylsilyl-protected alkyne group allows for controlled deprotection and extension of π-conjugated systems. Also employed in the development of sensors and functionalized surfaces in materials science.
