Used primarily as an intermediate in the synthesis of sulfonamide-based compounds, particularly in the pharmaceutical industry. It plays a key role in the production of certain antibiotics, antidiabetic agents, and antimicrobial drugs. The compound is also employed in the preparation of agrochemicals, including herbicides and pesticides, due to its ability to modify molecular reactivity in active ingredients. Additionally, it serves as a sulfonating agent in organic synthesis, facilitating the introduction of sulfonyl groups into various substrates for enhanced chemical stability and biological activity.
