Description

2,2'-[Carbonylbis(Thio)]Bis-Ethanesulfonic Acid Sodium Salt is a specialized organosulfur compound featuring a central carbonyl group flanked by two thioether-linked ethanesulfonate moieties. This unique structure makes it a valuable intermediate and reagent for the synthesis of functional materials and bioactive molecules, particularly where water solubility and specific sulfur-based reactivity are required. It is primarily sought by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications in drug discovery, ligand synthesis, and as a building block for functional polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those targeting enzymes or receptors where the disulfide-like linkage is critical.
• Ligand and Chelator Synthesis: Serves as a precursor for creating water-soluble chelating agents or ligands for metal catalysis and diagnostic imaging.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce sulfonate groups and specific reactive sites into polymers, enhancing hydrophilicity or ionic character.
• Bioconjugation Chemistry: Utilized as a linker or reagent for modifying proteins, peptides, or other biomolecules to improve solubility or attach labels.
• Agrochemical Research: Employed in the development of new herbicides, fungicides, or plant growth regulators that incorporate sulfur-based functional groups.
• Electrolyte Additive: Investigated for use in advanced battery systems where sulfonate salts can influence electrolyte stability and performance.
