Used as a key intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. Its alkyne and hydroxyl functional groups allow for versatile modifications via click chemistry, especially in forming triazole rings through copper-catalyzed azide-alkyne cycloaddition (CuAAC). This makes it valuable in medicinal chemistry for building drug-like compounds and in bioconjugation for labeling biomolecules. Also employed in the synthesis of pyridine-containing ligands for catalysis and materials science.
