Sodium Metabisulfite (Na₂S₂O₅) is a widely used inorganic compound known for its stable chemical properties. It typically appears as a white to light yellow crystalline powder and releases a characteristic sulfur dioxide smell during use.
This material is commonly applied as a preservative, antioxidant, and reducing agent across various industrial processes. Its functional properties make it suitable for applications where oxidation control, product stability, and chemical reduction are required.
Due to its consistent composition and controlled purity parameters, sodium metabisulfite is frequently selected in sectors such as food processing, water treatment, and chemical manufacturing.
