Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor agonists and antagonists. Plays a role in the production of agrochemicals, including certain insecticides and herbicides, due to its ability to enhance bioactivity in active ingredients. Also employed in the preparation of functionalized pyridine derivatives for use in medicinal chemistry and materials science. Its nitrile and carboxylic acid groups allow for versatile chemical modifications, making it valuable in research and development of new bioactive compounds.
