Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for targeted therapies. It is also employed in the production of organic compounds for research purposes, especially in the field of medicinal chemistry, where its structure is utilized to create molecules with potential biological activity. Additionally, it finds application in the preparation of advanced materials, such as polymers and coatings, due to its reactive ethynyl group, which allows for further functionalization and cross-linking.
