Methanesulfonic Acid(MSA) CAS 75-75-2
Sinochem is a major Methanesulfonic Acid & MSA supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Methanesulfonic Acid & MSA.
Methanesulfonic acid (MSA) is a strong organic acid, a colorless liquid at room temperature. It’s a non-oxidizing, biodegradable catalyst used in electroplating and organic synthesis.
- High Metal Salt Solubility: MSA metal salts are highly soluble in water, offering significant advantages in applications such as electroplating and metal leaching.
- Biodegradable: MSA readily biodegrades and has low aquatic toxicity, making it a more environmentally friendly choice for industrial processes and waste disposal.
- Strong Acidity: It provides the strong acidity required for many reactions without the severe side effects of concentrated mineral acids.

Mesylic acid Applications
MSA 70%:
1. When used in conjunction with its salts, it can produce electroplated coatings with varying performance characteristics. It is widely used in the electroplating of electronic circuit boards, automotive bearings, electronic connectors, and electronic CP wires. It can also be used for tinning cold-rolled and hot-rolled steel sheets.
2. It can be used as a catalyst in organic reactions.
3. It can be used as a specialty solvent.
MSA 99%:
It can be used as a catalyst for alkyl polymerization and other reactions.
