Used primarily as a pharmaceutical intermediate in the synthesis of nicotinic receptor agonists and antagonists. Plays a key role in developing compounds for neurological disorders such as Alzheimer's, Parkinson's, and depression. Also utilized in the production of agrochemicals, particularly insecticides targeting insect nicotinic acetylcholine receptors. Its structure supports the development of selective bioactive molecules due to its ability to mimic natural neurotransmitters. Commonly employed in research settings for structure-activity relationship (SAR) studies of pyridine-based drugs.
