Market Overview of Sodium Nitrite and Sodium Thiosulfate

Sodium Nitrite (NaNO₂)

Sodium nitrite is widely used as a preservative and color fixative in cured meats, as an antioxidant in food applications, and as a critical reagent in cyanide detoxification in medical settings. Its pharmaceutical grade must meet strict purity standards to avoid toxic contaminants, primarily nitrosamines.

Sodium Thiosulfate (Na₂S₂O₃)

Sodium thiosulfate finds extensive use in managing cyanide poisoning, in water treatment, and as an analytical reagent. Pharmaceutical-grade sodium thiosulfate ensures high purity levels, predominantly grade USP or EP compliant, suitable for intravenous administration and certified within regulatory frameworks such as the U.S. Pharmacopeia (USP) and European Pharmacopoeia (EP).
