Used primarily as an intermediate in the synthesis of pharmaceuticals, especially in the development of nicotinic receptor agonists and other neuroactive compounds. It serves as a building block in the preparation of more complex pyridine derivatives with potential applications in treating neurological disorders such as Alzheimer's and Parkinson's disease. Also employed in agrochemical synthesis for creating novel pesticides and herbicides due to its electron-deficient aromatic structure, which enhances binding to biological targets. Its nitro group allows for further functionalization through reduction to amines, enabling diverse derivatization in medicinal chemistry research.
