This chemical is primarily used as an intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. It serves as a key building block in the creation of sulfonamide derivatives, which are widely utilized in the development of antibacterial and antifungal agents. Additionally, it is employed in the manufacture of dyes and pigments, where its sulfonyl chloride group facilitates the introduction of sulfonamide or sulfonate functionalities into the target molecules. Its reactivity also makes it valuable in research and development for designing new chemical entities with potential biological activity.
