Sodium Metabisulfite
Industrial Applications
Sodium Metabisulfite is extensively used in the pharmaceutical industry as a preservative and antioxidant. It helps prevent oxidation and maintain the stability of drug formulations, particularly in injectable solutions, topical preparations, and oral medications. Additionally, it serves as a reducing agent to preserve the potency of sensitive active pharmaceutical ingredients.
Physical Properties
Sodium Metabisulfite is an inorganic compound that typically appears as a white to yellowish crystalline powder. It is highly soluble in water, releasing sulfur dioxide upon dissolution.
