Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and other central nervous system agents. Its structure allows for selective functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with high potency. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex pyridine-based molecules. Also utilized in agrochemicals for the design of novel pesticides due to its ability to enhance bioactivity and binding selectivity. The hydrochloride salt form improves stability and handling during industrial-scale reactions.
