CAS 75-75-2: Acide méthanesulfonique
Description :
Acide méthanesulfonique (MSA), avec le numéro CAS 75-75-2, est un liquide incolore et inodore qui est hautement soluble dans l'eau et dans les solvants organiques polaires. C'est un acide fort, caractérisé par sa capacité à donner des protons (ions H⁺) facilement, ce qui en fait un réactif utile dans diverses réactions chimiques. Le MSA a un point d'ébullition relativement bas et est stable dans des conditions normales, mais il peut se décomposer à des températures élevées. Sa structure chimique présente un groupe acide sulfonique (-SO₃H) attaché à un groupe méthyle (-CH₃), ce qui contribue à son acidité et à sa réactivité. Acide méthanesulfonique est souvent utilisé comme solvant, catalyseur et dans la synthèse de produits pharmaceutiques et d'agrochimiques. De plus, il est apprécié en électrochimie et comme agent de nettoyage en raison de sa capacité à dissoudre les oxydes métalliques et autres contaminants. Des précautions de sécurité sont nécessaires lors de la manipulation de l'MSA, car il peut provoquer des irritations cutanées et oculaires. Dans l'ensemble, Acide méthanesulfonique est un composé important tant dans les environnements industriels que de laboratoire.

CAS :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.

CAS :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.Formule :CH4O3SDegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :96.11 g/mol
