Used in the synthesis of pharmaceutical intermediates, particularly in the development of central nervous system agents and vasodilators. It serves as a building block in medicinal chemistry due to the presence of both sulfonamide and electron-rich aromatic functionalities, enabling further functionalization. Commonly employed in research settings for the preparation of bioactive molecules and analogs targeting cardiovascular and neurological conditions. Also utilized in the optimization of drug candidates where sulfonamide groups contribute to solubility and target binding.
