Used primarily in organic synthesis as a specialty alkyne building block, particularly in the development of ligands for transition metal catalysis. Its sterically hindered structure makes it valuable in the preparation of tailored catalysts for cross-coupling reactions. It also finds use in materials science for constructing rigid, conjugated frameworks in organic semiconductors and molecular electronics due to its stable triple bond and aromatic substituents. Additionally, it serves as a precursor in the synthesis of strained cyclic alkynes for bioorthogonal chemistry applications.
