Methylene Methanedisulfonate (MMDS) (CAS: 99591-74-9)

This product, Methyl methanesulfonate (MMDS, CAS 99591-74-9), is developed as a high-purity sulfur-containing organic reagent for advanced energy materials research, particularly in lithium-ion battery electrolyte formulations. As a key additive, it is commonly employed to modify the solid electrolyte interphase (SEI) and enhance cycling stability under high-voltage or high-temperature conditions. The compound’s sulfonate ester structure offers well-documented compatibility with carbonate-based solvents and lithium salts, making it a standard reference material in electrochemical studies. Available in gram-to-kilogram packaging (20 g to 1000 g), it provides flexibility for both laboratory-scale screening and process development. This product is also relevant in organic synthesis where selective methylating or sulfonylating agents are required. Its technical specifications support reproducible performance across varied experimental setups, aligning with the needs of researchers focused on electrolyte optimization and battery longevity.
