CAS 7631-90-5

Bisolfito di sodio

Descrizione:

Bisolfito di sodio, con la formula chimica NaHSO₃ e numero CAS 7631-90-5, è un composto inorganico che appare come un solido o polvere cristallina bianca. È altamente solubile in acqua, formando una soluzione leggermente acida. Bisolfito di sodio è comunemente usato come agente riducente in varie reazioni chimiche, in particolare nell'industria alimentare e delle bevande come conservante e antiossidante. Agisce prevenendo l'ossidazione, prolungando così la durata dei prodotti. Inoltre, è utilizzato in fotografia, trattamento delle acque e come reagente nella sintesi organica. Il composto ha un odore caratteristico di solfuro e può rilasciare gas anidride solforosa quando reagisce con acidi. Sebbene generalmente considerato sicuro in piccole quantità, può causare irritazione della pelle, degli occhi e delle vie respiratorie in caso di esposizione. Una corretta manipolazione e conservazione sono essenziali per mitigare eventuali pericoli potenziali associati al suo uso.

Sodium bisulfite - 38%-40% solution

CAS: 7631-90-5

Sodium bisulfite is a chemical that is commonly used in the laboratory to inhibit the activity of DNA polymerases. It has been used in vitro to model infectious diseases, such as HIV, by simulating viral replication. This chemical has also been shown to be effective in chemiluminescence methods for the detection of polysaccharides and proteins. The optimum concentration for sodium bisulfite is 38-40%, and it should not be used at concentrations above 40%. Sodium bisulfite can cause bowel disease when consumed by humans at high doses or after long-term exposure. It has also been shown to be toxic to aquatic organisms at high concentrations. Sodium bisulfite is a strong reducing agent that can reduce copper ions into copper metal and iron ions into iron metal. This chemical has been studied extensively for its analytical applications, including its use in determining levels of dNTPs present in wastewater samples. Sodium bisulfite can react with DNA templates if they are present during the reaction solution
