Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and anti-inflammatory agents. Commonly employed in agrochemical formulations for the production of herbicides and insecticides due to its reactivity and stability in multi-step organic transformations. Also utilized in research laboratories for constructing nitrogen-containing heterocyclic compounds. Its ester and halogen functionalities allow for selective reactions, making it valuable in combinatorial chemistry and drug discovery.
