Application:
Methanesulfonic Acid (MSA) (CAS: 75-75-2) is a strong organic acid. It is considered a green acid as it is less toxic and corrosive in comparison to mineral acids. The aqueous MSA solution has been considered a model electrolyte for electrochemical processes. Methanesulfonic Acid is an alkanesulfonic acid in which the alkyl group directly linked to the sulfo functionality is methyl. It has a role as an Escherichia coli metabolite. It is an alkanesulfonic acid and a one-carbon compound. It is a conjugate acid of a methanesulfonate. Methanesulfonic Acid, the simplest alkanesulfonic acid. It will not subject to decomposition in boiling water and hot alkaline solution. It also has strong corrosion effect against the metal iron, copper and lead. Methanesulfonic Acid is a raw material for medicine and pesticide. It can also be used as dehydrating agent, curing accelerator for coating, treating agent for fiber, solvent, catalysis, and esterification as well as polymerization reaction. It can be used as solvent, alkylation, catalyst of esterification and polymerization, also used in medicine and electroplating industry. It can also be applied to oxidation. Methanesulfonic Acid is used in the electroplating industry and for organic syntheses, in particular as a catalyst for alkylations, esterifications, and polymerizations. Beyond that, Methanesulfonic Acid is used as a starting material for the preparation of methanesulfonyl chloride. Methanesulfonic Acid has been developed as an esterification catalyst in place of sulfuric acid for the synthesis of resins in paints and coatings. One of the major advantages of Methanesulfonic Acid over sulfuric acid is that it is not an oxidizing species. Methanesulfonic Acid is used as a catalyst in organic reactions namely esterification, alkylation and condensation reactions due to its non- volatile nature and solubility in organic solvents. It is also involved in the production of starch esters, wax oxidate esters, benzoic acid esters, phenolic esters, or alkyl esters. It reacts with sodium borohydride in presence of polar solvent tetrahydrofuran to prepare borane-tetrahydrofuran complex. It finds application in batteries, because of its purity and chloride absence. In pharmaceutical industry, it is used for the manufacturing of active pharmaceutical ingredients like telmisartan and eprosartan. It is useful in ion chromatography and is a source of carbon and energy for some gram-negative methylotropic bacteria.It is involved in the deprotection of peptides.
