Product Description:
Used as a key intermediate in organic synthesis, particularly in the preparation of complex molecules through alkyne coupling reactions. Its tosylate group acts as a good leaving group, enabling nucleophilic substitution reactions, while the terminal alkyne functionality allows participation in metal-catalyzed reactions such as Sonogashira coupling. Commonly employed in the synthesis of pharmaceuticals, agrochemicals, and functional materials where precise molecular architecture is required. Also utilized in research settings for the construction of conjugated systems and natural product analogs.
