一般描述

铁氰化钾(III)是一种钾盐，广泛用作重铬酸钾滴定中的外指示剂。一种包含铁氰化钾辅助的酶电极的传感器已有报道，其可用于估计样品中的麦芽糖和葡萄糖含量。在阴极电解液中添加铁氰化钾可以改善微生物燃料电池（MFC）中的功率产生。

应用

铁氰化钾(III)已用于：
  • 制备X-gal染色溶液，用于对受损新生小鼠心脏的冷冻切片组织进行染色。
  • Issopus officinalis的冷冻干燥乙醇提取物的还原力测定。
  • 与戊二醛和四氧化锇组合用于在环氧树脂包埋之前对生物样品进行后固定。

  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).
