Used primarily as a reagent in organic synthesis, this chemical is instrumental in the preparation of sulfonamides, which are crucial in pharmaceutical applications. It acts as a protecting group for amines during complex molecule constructions, ensuring selective reactions without disrupting other functional groups. Additionally, it finds utility in the synthesis of dyes and pigments, where it contributes to the development of colorants with specific properties. Its role in modifying polymers to enhance their characteristics is also notable, particularly in creating materials with improved durability and resistance.
