This chemical is primarily used in organic synthesis as an intermediate for the production of more complex compounds. It is particularly valuable in the development of pharmaceuticals, where it serves as a building block for active pharmaceutical ingredients (APIs). Its reactive chlorosulfonyl and ester groups make it suitable for creating sulfonamide derivatives, which are often found in drugs with antibacterial, anti-inflammatory, or diuretic properties. Additionally, it is utilized in research laboratories for synthesizing nitroaromatic compounds, which are important in the study of chemical reactions and material science. Its applications also extend to the production of dyes and pigments, where its nitro group contributes to color formation.
