Used primarily as an intermediate in organic synthesis, this compound plays a key role in the preparation of pharmaceuticals and biologically active molecules. Its aldehyde and nitro functional groups allow for diverse chemical transformations, making it valuable in constructing complex ring systems and heterocycles. It is often employed in the development of dyes, fragrances, and specialty chemicals due to its reactivity in condensation and cyclization reactions. Additionally, it serves as a building block in the synthesis of certain neuroactive compounds and photoresponsive materials, where the ortho-nitro group contributes to light-sensitive behavior.
