Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and central nervous system agents. It serves as a building block for more complex pyridine derivatives with biological activity. Commonly employed in research settings for the preparation of chiral catalysts and asymmetric synthesis due to the presence of the chloroethyl functional group. Also utilized in agrochemical research for the design of novel pesticides and herbicides where pyridine-based structures enhance target specificity and stability.
