Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of substituted aromatic compounds. Its electrophilic nature makes it suitable for cross-coupling reactions, such as Suzuki and Heck reactions, enabling the formation of carbon-carbon bonds in complex molecule assembly. Also employed in the development of dyes and fluorescent probes due to its nitro and aldehyde functional groups, which can be modified for specific optical properties. Commonly utilized in research settings for the construction of heterocyclic systems and bioactive molecules.
