Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its alkyne and aryl bromide functionalities allow for versatile coupling reactions, such as Sonogashira and Suzuki couplings, enabling the construction of complex organic molecules. Commonly employed in the development of functional materials, including liquid crystals and conjugated polymers for electronic applications. Also utilized in click chemistry due to the presence of the alkyne group, facilitating rapid and selective molecular assembly in drug discovery and bioconjugation.
