Description

Sodium Methane Disulfonate (CAS No. 5799-70-2) is a high-purity organic sulfonate compound with the molecular formula CH₂Na₂O₆S₂. Also known as disodium methanedisulfonate, this white crystalline powder is widely utilized in chemical synthesis, catalysis, and specialty electrolyte formulations. With excellent water solubility and thermal stability, it serves as a versatile intermediate in pharmaceutical, agrochemical, and battery material research. Our product is rigorously tested to meet >98% purity standards (HPLC) with trace metal analysis available upon request. Suitable for use under inert conditions due to its hygroscopic nature. Packaged in amber glass bottles or moisture-resistant poly containers with optional argon atmosphere sealing for sensitive applications.

Application

Sodium Methane Disulfonate functions as a key electrolyte additive in lithium-ion battery systems, improving cycle stability at high voltages. Researchers employ it as a sulfonation agent in organic synthesis for introducing sulfonate groups to aromatic compounds. In industrial water treatment, it acts as a scale inhibitor due to its chelating properties with divalent cations. The compound also finds use in specialty detergent formulations where thermal-stable anionic character is required.
