Used primarily as a building block in organic synthesis, this compound serves in the preparation of more complex molecules, especially in pharmaceutical and agrochemical industries. Its alkyne functionality combined with a chloro substituent allows for selective reactions, such as cross-coupling and nucleophilic substitution, enabling the construction of carbon-carbon bonds. It is also employed in the synthesis of conjugated systems and functionalized hydrocarbons used in materials science. Due to its reactivity, it is valuable in research settings for developing intermediates in specialty chemicals.
