Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and central nervous system agents. Its structure allows for the formation of nitrogen-containing heterocycles, which are common motifs in drug development. Also employed in research settings for the preparation of propargylamine derivatives, which show potential in treating neurodegenerative diseases due to their ability to modulate enzyme activity such as MAO-B inhibition. Commonly utilized in organic synthesis for click chemistry applications, where the alkyne group participates in copper-catalyzed azide-alkyne cycloaddition reactions to form triazole rings, useful in bioconjugation and medicinal chemistry.
