Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antihistamines and nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block in organic reactions where the nitro and chloro functional groups allow for further chemical modifications, such as reductions and nucleophilic substitutions. Its structure is valuable in forming more complex molecules in medicinal chemistry and agrochemical research. Also employed in the development of dyes and photochemical compounds due to its aromatic ketone properties and light absorption characteristics.
