Methanesulfonic Acid CAS 75-75-2 : For Metal Surface Treatment & Textile Soaping Agents

Chemical Name: Methanesulfonic Acid
Other Name: MSA
CAS: 75-75-2
Molecular Formula: CH₃SO₃H

Product Description
Methanesulfonic acid is a versatile strong organic acid widely used in fields ranging from chemical and biofuel synthesis to industrial cleaning and metal surface treatment in the electronics industry. The applications of methanesulfonic acid primarily rely on its ability to chelate metal ions and its solubility in water. Metal salts of methanesulfonic acid, such as its calcium, barium, and strontium salts, exhibit exceptionally high solubility in water—up to 500–700 g/L—which is unparalleled by other acids.

Product Applications:

Cleaning and descaling of oilfield production pipelines, including drilling filter cake removal, injection well cleaning, naphthenate scale dissolution, acidification, and fracturing.

Electrochemical industries, such as electroplating, batteries, and printed circuit boards.

Metal refining and electrolytic metallurgy.

Catalyst in the chemical industry, serving as a high-end alternative stripping agent that does not damage substrate materials.

99% solid-content methanesulfonic acid is used as a pharmaceutical intermediate in the production of methanesulfonic anhydride, sodium trifluoromethanesulfonate, fluconazole, phentolamine mesylate, etc.

Methanesulfonic acid is an important intermediate in organic synthesis and pharmaceuticals, commonly employed as a solvent, alkylating agent, and esterification reagent in organic synthesis.

Used as a solvent and catalyst in alkylation, esterification, and polymerization reactions.

A sustainable alternative to traditional acids. In recent years, methanesulfonic acid has proven to be an increasingly popular substitute for fluoroboric acid or phenolsulfonic acid.

Battery electrolyte.

Glass etching solution.

An ideal leveling and brightening agent.
