General description

Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations. A sensor containing potassium ferricyanide assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide in the catholyte can improve the generation of power in microbial fuel cells (MFCs).

Application

Potassium ferricyanide(III) has been used:
  • To prepare the X-gal staining solution for staining cryosectioned tissues of injured neonatal mouse heart.
  • Reducing power assay of freeze-dried ethanolic extract of Issopus officinalis.
  • In combination with glutaraldehyde and osmium tetroxide for post-fixation of biological samples prior to epoxy embedding.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. There are several other Potassium ferricyanide(III) products available.  How does Product No. 702587 differ from other chemically identical products?

    Specifications are available for each product.  Product No. 702587 is the only Potassium ferricyanide(III) product available from Sigma-Aldrich that has a particle size of <10 μm. The other products are generally described as either powders or crystals.

  6. After diluting Potassium Ferricyanide, Product 702587, with water, I observed that the solution turned blue, and not the typical brownish-yellow color. Is that a problem?

    This likely means that your water contains some iron (II) (i.e., ferrous iron). Potassium ferricyanide and hydrochloric acid are actually the reagents typically used to demonstrate ferrous salts using the Turnbull Blue reaction.

  7. Is there a reference for using Potassium Ferricyanide, Product 702587, in the Turnbull Blue reaction?

    There are many variations on the basic Turnbull Blue technique. A commonly performed procedure is the procedure of Lillie and Geer. See Lillie, R.D. & Geer, J.C. On the relation of enterosiderosis pigments of man and guinea pig, melanosis and melanosis of colon and villi and the intestinal iron update and storage mechanism.  American Journal of Pathology, 47, 965-1007 (1965).
