Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its alkyne functionality allows for efficient coupling reactions, such as Sonogashira or click chemistry, enabling rapid assembly of complex molecules. Also employed in the preparation of functionalized ligands for catalysis and in materials science for constructing conjugated organic frameworks with electronic properties. Its structural motif is valuable in medicinal chemistry for enhancing binding affinity and selectivity in drug candidates.
