Description

n-(4-Bromophenyl)Methanesulfonamide is a high-purity (97%) organic intermediate featuring a brominated aromatic ring coupled with a methanesulfonamide functional group. This specific molecular architecture makes it a valuable building block for synthesizing more complex chemical entities, particularly in pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working in fine chemical and active pharmaceutical ingredient (API) manufacturing. The compound's structure offers versatile sites for further functionalization, enabling the creation of novel sulfonamide-based compounds with targeted biological or material properties.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of potential drug candidates, especially those requiring sulfonamide pharmacophores for biological activity.
• Agrochemical Research: Used in developing new herbicides, fungicides, or insecticides where the bromophenyl-sulfonamide moiety can contribute to efficacy.
• Material Science: Acts as a monomer or functional additive in the research of advanced polymers and specialty materials.
• Chemical Synthesis: Employed in cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) due to the reactive bromine atom, facilitating carbon-carbon and carbon-heteroatom bond formation.
• Ligand & Catalyst Development: Useful for creating novel ligands for metal catalysis or as a structural component in organocatalysts.
• Life Sciences & Biochemistry: Potential use in designing molecular probes or enzyme inhibitors for biochemical studies.
