This chemical is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its sulfonyl chloride group makes it a valuable reagent for introducing sulfonamide functionalities into molecules, which are often found in drugs with antibacterial, antiviral, or anti-inflammatory properties. Additionally, it can be utilized in the development of dyes and pigments due to its ability to form stable covalent bonds with other organic compounds. Its application extends to research settings, where it serves as a building block for creating more complex chemical structures in medicinal chemistry and material science.
