Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It plays a role in the development of active pharmaceutical ingredients (APIs) due to its ethynyl and nitrile functional groups, which are versatile for further chemical modifications. Additionally, it is employed in material science for the creation of advanced polymers and coatings, leveraging its ability to form stable bonds and enhance material properties. Its applications also extend to the field of organic electronics, where it contributes to the synthesis of conductive and semiconductive materials.
