Our Methane sulfonic acid (MSA) is available in two industry concentrations: 70% MSA and 99% MSA. Engineered for exceptional performance, both deliver high purity and low impurties with superior physical properyties.
CAS No.: 75-75-2
Molecular Formula: CH₄O₃S
Molecular Weight: 96.10 g/mol
Synonyms: Methylsulfonic acid, MSA
📦 Features
MSA 70: Optimized for electronic applications with ultra-low chloride ions and sulfates, preventing plating defects.
MSA 99: Ultra high purity, minimal heavy metals, ideal for pharmaceutical catalysis and sensitive organic synthesis. High-concentration formula (density: ~1.48 g/cm³) for efficient reactions.
