Used primarily in organic synthesis, it serves as a key intermediate in the production of pharmaceuticals and agrochemicals. Its sulfonamide group is particularly valuable in creating compounds with antibacterial or antifungal properties. Additionally, it is employed in the development of dyes and pigments due to its aromatic structure, which can enhance color stability. In research, it is utilized to study sulfonamide-based reactions and their mechanisms. Its methoxy groups also make it a useful building block for designing molecules with specific electronic properties.
