Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and development of functional materials. The hydroxyl group enables further derivatization, such as esterification or ether formation, facilitating its incorporation into more complex molecular architectures. Commonly employed in the synthesis of kinase inhibitors and other therapeutic agents where aryl alkyne motifs are required. Also utilized in materials science for constructing conjugated systems and molecular building blocks in supramolecular chemistry.
