Used as a building block in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and combinatorial chemistry. The amine group enables easy conjugation with carbonyl compounds or carboxylic acid derivatives, facilitating the formation of amides, imines, or Schiff bases. It is also employed in the synthesis of propargylamine-based inhibitors of enzymes like monoamine oxidase (MAO), which are relevant in treating neurological disorders such as Parkinson’s and Alzheimer’s disease. Additionally, it serves as a precursor in the preparation of fluorescent probes and functionalized polymers due to its reactivity and structural features.
