Description

1, 2-Benzenedisulfonyl Fluoride is a high-purity, reactive organosulfur compound primarily used as a key synthetic intermediate. Its value lies in its dual sulfonyl fluoride functional groups, which enable efficient derivatization and cross-linking reactions in advanced chemical synthesis. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel sulfonamide-based compounds and functional materials.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of biologically active sulfonamide drugs and protease inhibitors.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and plant growth regulators containing sulfonyl groups.
• Polymer Modification: Serves as a cross-linking agent or functional monomer for producing specialty polymers with enhanced thermal or chemical resistance.
• Chemical Biology & Proteomics: Employed as a reactive probe in activity-based protein profiling (ABPP) and chemoproteomic studies due to its electrophilic warhead.
• Material Science Research: Utilized in the development of advanced materials, such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), with sulfonyl fluoride linkers.
• Dye & Pigment Manufacturing: Acts as an intermediate in the production of certain sulfonated dyes and colorants.
