Methane Sulfonic Acid (MSA)

Methane Sulfonic Acid (MSA) is a strong, non-oxidizing organic acid known for its high acidity, excellent solubility, and environmental friendliness. It offers superior metal cleaning and catalytic performance in chemical processes. With low toxicity, high stability, and biodegradability, MSA is widely used in electroplating, pharmaceuticals, catalysts, and industrial formulations as a replacement for mineral acids like sulfuric acid and hydrochloric acid.

Applications

• Electroplating and metal surface treatment

• Catalyst for esterification and polymerization

• Pharmaceutical and fine chemical synthesis

• Electronics cleaning and PCB treatment

• Battery electrolytes

• Biomass processing and green chemistry applications

• Acidizing agent in oil & gas applications

• Alternative to conventional mineral acids
