Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its alkyne functionality allows for efficient coupling reactions, such as Sonogashira or click chemistry, enabling rapid assembly of complex molecules in drug discovery. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance binding selectivity in target proteins. The bromine moiety facilitates further functionalization, making it valuable in combinatorial chemistry and library synthesis for high-throughput screening.
