Used in the synthesis of pharmaceutical compounds, particularly in the development of drugs targeting neurological disorders. It serves as a key intermediate in the creation of molecules that interact with neurotransmitter systems, potentially aiding in the treatment of conditions like depression or anxiety. Additionally, it is employed in organic chemistry research for constructing complex structures due to its ethynyl and amine functional groups, which enable versatile reactivity. Its applications also extend to materials science, where it contributes to the development of advanced polymers and coatings with enhanced properties.
