4-Ethynylbenzonitrile is used as a synthetic fragment and as a test compound for cross-coupling reactions. It is used in the study of hydrogen bond formation in multifunctional molecules due to the presence of four hydrogen bonding sites. It is also involved in the preparation of 4-[(trimethylsilyl)ethynyl]benzonitrile.
