Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of nicotinic receptor modulators. Its aldehyde and chlorine functionalities allow for selective chemical transformations, making it valuable in constructing complex heterocyclic systems. Commonly employed in the production of plant growth regulators and insecticides due to its ability to enhance bioactivity in final compounds. Also utilized in research for developing novel analogs with potential neuroactive properties.
