    Product Name: Sodium nitrite

    CAS No.: 7632-00-0

    EINECS No.: 231-555-9

    Molecular formula: NNaO2

    Molecular weight: 69

    Uses: Mainly used as raw materials for manufacturing base compounds, azo dyes, etc.; used as mordant and bleaching agent for fabric dyeing; metal heat treatment agent; cement early strength agent, antifreeze, etc. Mainly used in the pharmaceutical and chemical industries. Sodium nitrite is not only an antifreeze chemical admixture for early-strength cement concrete, but also a catalyst for the hydration and hardening of early-strength cement.

    Sodium nitrite is also a corrosion inhibitor for metals. After the surface of the metal is dipped with sodium nitrite solution, it can be corrosion-inhibited for about half a year. Sodium nitrite is often used as a rust inhibitor for castings.
