Product name: Methanesulfonic Chloride (MSC)
Chemical Formula : [CH3SO2Cl]
Methane Sulfonyl Chloride, CH3SO2Cl is a versatile, reactive chemical which offers a mesyl group (CH3S02-) for substitution in a number of reactions. Methane Sulfonyl Chloride, an acid chloride, undergoes reactions which typify this class of compounds, such as replacement of hydroxyl, amino and active alpha hydrogens, hydrolysis, etc
Toxic. Corrosive. Inhalation Hazard. Molecular Weight: 114.6. Odor: Heavy Stimulant Odor. Appearance: Transparent Oil Liquid. Cas # 124-63-0, Un # 3246.
MSC is made from the chlorination of DMDS. The process is clean, and no detectable impurities of methyl methane thiosulfonate. It is ideal for pharmaceutical applications. Used as catalyst, chlorinating agent, firming agent, stabilizer or as an intermediate for dyes, pharmaceuticals and pesticides.
Methane Sulfonic Acid 70% in Electrochemical Applications:
· Replacement for fluoboric acid and fluoborates in tin/lead plating
· Wire and steel strip tin plating
· Metal finishing of silver, copper, nickel and palladium
· Immersion and spray stripping
· Lead recovery from scrap batteries
· Electrolytic stripping
· Regenerating ion exchange resins
Methane Sulfonic Acid 70% is an excellent catalyst for esterification, alkylation and condensation reactions. Methane Sulfonic Acid yields purer and lower color esters than both sulfuric and para-toluene sulfonic acids. Unlike titanate catalysts, Methane Sulfonic Acid can be used at low temperatures.
Key Benefits of Methane Sulfonic Acid in Esterifcation:
· Low molecular weight
· Pure and non-oxidizing
· Limited by-products
· High thermal stability
· A clear rag layer
· Easily handled
· Less corrosive than H2SO4
Methane Sulfonic Acid is the catalyst of choice for: acetates, acrylates, phthalates, fatty acid esters and thioglycolates.
