In the world of industrial chemicals, few compounds offer the unique combination of strength, versatility, and environmental friendliness as Methane Sulfonic Acid (MSA). Known by its chemical formula CH4O3S and CAS number 75-75-2, MSA is an alkanesulfonic acid that has become an indispensable tool across a vast array of applications. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing the highest quality Methane Sulfonic Acid, available in 70% and 90% concentrations, to meet the rigorous demands of modern industry.

Understanding Methane Sulfonic Acid (MSA)

Methane Sulfonic Acid is a colorless, odorless liquid that is considered a strong organic acid. However, unlike many of its inorganic counterparts like sulfuric or hydrochloric acid, it is non-oxidizing. This property, combined with its high thermal stability and low vapor pressure, makes it a safer and easier-to-handle alternative in many processes. One of its most celebrated attributes is its biodegradability; MSA breaks down into naturally occurring sulfate and carbon dioxide, posing a minimal environmental burden. Its high solubility in water and various organic solvents further enhances its utility.

Key Properties:
CAS No.: 75-75-2
Formula: CH4O3S
Molecular Weight: 96.10
Appearance: Colorless Liquid
Melting Point: 17-20 °C
Density: ~1.48 g/mL
Solubility: Highly soluble in water

A Superior Choice in Electroplating

The electroplating industry has widely adopted Methane Sulfonic Acid, particularly for tin and tin-lead alloy plating. Traditionally, acids like fluoroboric acid were used, but they posed significant environmental and safety hazards. MSA-based electrolytes have emerged as a superior alternative. The high solubility of its metal salts (mesylates) allows for the formulation of baths with high metal concentrations, leading to faster plating rates and increased productivity.

The deposits produced from MSA baths are fine-grained, smooth, and uniform, which is critical for the electronics industry in applications like printed circuit boards (PCBs) and connectors. Furthermore, the waste streams from MSA-based processes are significantly easier to treat than those containing fluoroborates. This shift not only improves the quality of the end product but also enhances operational safety and reduces the environmental footprint of the entire process. As a reliable supplier, we ensure our MSA meets the stringent purity requirements for these sensitive applications.

A Powerful Catalyst in Organic Synthesis

Methane Sulfonic Acid is a highly effective Brønsted acid catalyst used in a multitude of organic reactions. Its strong acidity drives reactions like esterification, alkylation, and polymerization efficiently. In the production of biodiesel, MSA is used to catalyze the esterification of free fatty acids in feedstock, improving yields and allowing for the use of more varied and cost-effective raw materials. Its non-oxidizing nature minimizes the formation of unwanted by-products, resulting in a purer final product with better color stability.

In the pharmaceutical and fine chemical sectors, MSA serves as a catalyst for creating complex molecules and can also be used as a reagent or solvent. Its ability to facilitate reactions and its favorable environmental profile make it an excellent choice for developing greener, more sustainable chemical processes. If you are looking to buy a high-performance catalyst, our MSA is the optimal solution.

Effective and Green Industrial Cleaning

MSA's power as a strong acid makes it an excellent agent for industrial cleaning and descaling. It effectively dissolves mineral scales (e.g., carbonates), metal oxides, and rust. Unlike other strong acids, it is less corrosive to metals, especially stainless steel, and is safe to use on sensitive surfaces like ceramics and tiles. This makes it a key ingredient in many industrial rust removers and cleaning formulations. The high solubility of the resulting metal mesylate salts prevents them from re-depositing on the cleaned surface, ensuring a thorough cleaning process. Companies looking for an attractive price point for a green and effective cleaning agent are increasingly turning to MSA.

Diverse Applications Across Industries

The utility of Methane Sulfonic Acid extends even further:

• Agrochemicals: Used as an intermediate in the synthesis of certain pesticides and herbicides.
• Petroleum Refining: Employed in some refining processes and as an additive in lube oils.
• Polymer and Plastic Industry: Acts as a curing agent and catalyst in the production of various plastics and resins.
• Pharmaceuticals: Used in the synthesis of Active Pharmaceutical Ingredients (APIs) and for the formation of pharmacologically acceptable salts to enhance drug stability and solubility.
