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.
