    Ferrozine Sodium CAS 69898-45-9

    Ferrozine Sodium (CAS 69898-45-9) is a water-soluble analytical reagent widely used for the spectrophotometric determination of ferrous iron (Fe²⁺). It forms a stable, colored complex with iron ions, enabling precise quantitative analysis in environmental testing, water analysis, and laboratory research.

    In commercial supply, Ferrozine Sodium is typically provided as a solid powder suitable for preparation of analytical solutions. It is supplied for laboratory and reagent use rather than bulk industrial processing. Standard packaging is available, with documentation such as COA, TDS, and SDS provided to support analytical and handling requirements.

    FAQ - Technical & Supply Chain

    • Q:

      What is Ferrozine Sodium CAS 69898-45-9?

      A: Ferrozine Sodium is the monosodium salt form of ferrozine, a water-soluble colorimetric reagent with the molecular formula C20H13N4NaO6S2. It is supplied as a powder and is used mainly for detecting and quantifying ferrous iron in analytical and biochemical work.
    • Q:

      How does Ferrozine Sodium detect iron?

      A: It reacts selectively with Fe2+ ions to form a stable magenta complex. The colored complex can be measured by UV-visible spectrophotometry, allowing ferrous iron to be quantified without requiring organic extraction.
    • Q:

      What wavelength is used for the Fe2+-Ferrozine complex?

      A: The Fe2+-Ferrozine complex is commonly measured at approximately 562 nm. Absorbance at this wavelength is used to calculate the ferrous iron concentration in the sample.
    • Q:

      Is Ferrozine Sodium the same as PDT disulfonate?

      A: PDT disulfonate is a common synonym for the ferrozine compound represented by CAS 69898-45-9. Both names refer to the water-soluble triazine sulfonate reagent used for ferrous iron determination.
    • Q:

      How should Ferrozine Sodium be stored?

      A: Store the powder in tightly closed containers in a cool, dry, well-ventilated area, protected from light and moisture. Sealed storage helps preserve reagent stability for reproducible iron assays.
