Used as a key intermediate in the synthesis of various organic compounds, particularly in the pharmaceutical and agrochemical industries. It plays a crucial role in the development of sulfonamide-based drugs, which are widely used as antibiotics, diuretics, and antidiabetic agents. Additionally, it is employed in the production of herbicides and pesticides, where its sulfonyl chloride group facilitates the creation of active ingredients that target specific pests or weeds. Its reactivity makes it valuable in organic synthesis for introducing sulfonyl functionalities into complex molecules.
