CAS 75-75-2

Methanesulfonic acid

Description:

Methanesulfonic acid (MSA), with the CAS number 75-75-2, is a colorless, odorless liquid that is highly soluble in water and polar organic solvents. It is a strong acid, characterized by its ability to donate protons (H⁺ ions) readily, making it a useful reagent in various chemical reactions. MSA has a relatively low boiling point and is stable under normal conditions, but it can decompose at elevated temperatures. Its chemical structure features a sulfonic acid group (-SO₃H) attached to a methyl group (-CH₃), which contributes to its acidity and reactivity. Methanesulfonic acid is often used as a solvent, catalyst, and in the synthesis of pharmaceuticals and agrochemicals. Additionally, it is valued in electrochemistry and as a cleaning agent due to its ability to dissolve metal oxides and other contaminants. Safety precautions are necessary when handling MSA, as it can cause skin and eye irritation. Overall, methanesulfonic acid is an important compound in both industrial and laboratory settings.

Methanesulfonic acid - 70% aqueous solution

CAS: 75-75-2

Methanesulfonic acid is a strong oxidizing agent that has been used for the treatment of infectious diseases and to induce remission in inflammatory bowel disease. Methanesulfonic acid is used as an analytical reagent in biochemistry, organic chemistry, and analytical chemistry. It has been used to measure cortisol concentration in blood samples. Methanesulfonic acid has been shown to increase the transcriptional activity of NF-κB by inducing the phosphorylation of IκBα. This leads to increased transcription of genes encoding cytokines that are involved in inflammation, leading to physiological effects such as increased heart rate and blood pressure, which can be measured using electrochemical impedance spectroscopy.
