Used in organic synthesis as a building block for pharmaceuticals and fine chemicals. Its alkyne functionality allows participation in click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation. The aromatic and carboxylic acid groups enable derivatization into esters, amides, or heterocyclic compounds. It serves in the preparation of liquid crystals, fluorescent dyes, and conjugated materials for optoelectronics. Also explored in medicinal chemistry for designing kinase inhibitors and anti-inflammatory agents due to its structural similarity to bioactive stilbene derivatives.
