CAS 75-75-2: Acido metansolfonico
Descrizione:
Acido metansolfonico (MSA), con il numero CAS 75-75-2, è un liquido incolore e inodore che è altamente solubile in acqua e in solventi organici polari. È un acido forte, caratterizzato dalla sua capacità di donare protoni (ioni H⁺) facilmente, rendendolo un reagente utile in varie reazioni chimiche. L'MSA ha un punto di ebollizione relativamente basso ed è stabile in condizioni normali, ma può decomporsi a temperature elevate. La sua struttura chimica presenta un gruppo acido solfonico (-SO₃H) attaccato a un gruppo metile (-CH₃), che contribuisce alla sua acidità e reattività. Acido metansolfonico è spesso utilizzato come solvente, catalizzatore e nella sintesi di prodotti farmaceutici e agrochimici. Inoltre, è apprezzato in elettrochimica e come agente di pulizia grazie alla sua capacità di dissolvere ossidi metallici e altri contaminanti. Sono necessarie precauzioni di sicurezza quando si maneggia l'MSA, poiché può causare irritazione della pelle e degli occhi. In generale, Acido metansolfonico è un composto importante sia in contesti industriali che di laboratorio.

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.Formula:CH4O3SPurezza:Min. 95%Colore e forma:Clear LiquidPeso molecolare:96.11 g/mol
