Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its alkyne functionality allows for efficient coupling reactions, such as Sonogashira or click chemistry, enabling rapid assembly of complex molecules. Also employed in the production of agrochemicals and functional materials due to its ability to modify electronic properties in conjugated systems. Its pyridine core enhances binding affinity in biological targets, making it valuable in medicinal chemistry research.
