Natriumthiosulfat

Beschreibung:

Natriumthiosulfat, mit der CAS-Nummer 7772-98-7, ist eine anorganische Verbindung, die häufig durch die Formel Na2S2O3 dargestellt wird. Sie erscheint als weißer, kristalliner Feststoff, der hochlöslich in Wasser ist und eine farblose Lösung bildet. Natriumthiosulfat ist bekannt für seine reduzierenden Eigenschaften und wird häufig in verschiedenen Anwendungen eingesetzt, einschließlich Fotografie, Wasseraufbereitung und als Antidot gegen Cyanidvergiftung. Es wirkt, indem es toxisches Cyanid in eine weniger schädliche Verbindung umwandelt. Die Substanz wird auch in der analytischen Chemie als Titrator in Redoxreaktionen verwendet, insbesondere in iodometrischen Titrationen. Neben ihrer chemischen Reaktivität ist Natriumthiosulfat unter normalen Bedingungen relativ stabil, kann jedoch bei Kontakt mit starken Säuren oder Hitze zerfallen und Schwefeldioxid sowie andere Produkte freisetzen. Ihr Sicherheitsprofil zeigt, dass sie im Allgemeinen als ungiftig angesehen wird, obwohl sie bei Kontakt Haut- und Augenreizungen verursachen kann. Insgesamt ist Natriumthiosulfat eine vielseitige Verbindung mit erheblichem Nutzen sowohl in industriellen als auch in Laborumgebungen.

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.
