CAS 7772-98-7
:Thiosulfate de sodium
Description :
Thiosulfate de sodium, avec le numéro CAS 7772-98-7, est un composé inorganique couramment représenté par la formule Na2S2O3. Il apparaît sous la forme d'un solide cristallin blanc qui est hautement soluble dans l'eau, formant une solution incolore. Thiosulfate de sodium est connu pour ses propriétés réductrices et est souvent utilisé dans diverses applications, y compris la photographie, le traitement de l'eau et comme antidote contre l'intoxication au cyanure. Il agit en convertissant le cyanure toxique en un composé moins nocif. La substance est également utilisée en chimie analytique comme titrant dans les réactions redox, en particulier dans les titrages iodométriques. En plus de sa réactivité chimique, Thiosulfate de sodium est relativement stable dans des conditions normales, mais peut se décomposer lorsqu'il est exposé à des acides forts ou à la chaleur, libérant du dioxyde de soufre et d'autres produits. Son profil de sécurité indique qu'il est généralement considéré comme non toxique, bien qu'il puisse provoquer des irritations de la peau et des yeux au contact. Dans l'ensemble, Thiosulfate de sodium est un composé polyvalent avec une utilité significative tant dans les environnements industriels que de laboratoire.

CAS :<p>Sodium thiosulfate is a salt that is used as an antimicrobial agent. It has been shown to inhibit the toll-like receptor 4 (TLR4) and TLR2, which are important in the innate immune response. It has also been shown to suppress inflammation and tumor formation in vitro and in vivo. Sodium thiosulfate has been shown to inhibit the growth of squamous carcinoma cells by inducing apoptosis. The anti-cancer effect of sodium thiosulfate is due to its ability to reduce oxidative stress and increase antioxidant activity in cancer cells. It also inhibits potassium dichromate induced cancer cell proliferation by reducing redox potential. This salt may be useful for treating malignant brain tumors, where it has been shown to inhibit glioma cell proliferation, induce apoptosis, and reduce metastasis via reduction of angiogenesis.</p>Formule :Na2S2O3Degré de pureté :Min. 97%Masse moléculaire :158.11 g/mol
