Descripción general

Potassium hexacyanoferrate(II) trihydrate, commonly known as potassium ferrocyanide, is a commonly used anticaking agent. Its cytotoxic and genotoxic effect has been evaluated. The growth of chemical garden in aqueous potassium hexacyanoferrate solution droplets on a superhydrophobic surface has been reported. The inhibition efficiency of potassium ferrocyanide in phosphoric acid solution against the corrosion of mild steel has been investigated.[1]

Aplicación

Potassium hexacyanoferrate(II) trihydrate may be used in the following processes:
  • Preparation of Carrez I solution.[2]
  • Milk sample preparation for gold nanoparticles (AuNPs) based colorimetric detection of melamine.[3]
  • Preparation of ferrocyanide/ferricyanide reaction, a redox pair solution for electrochemical testing.[4]

Questions

1–3 of 3 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. which potassium ferrocyanide (K4Fe(CN)6.3H2O) in your listing is suitable for perls stain in histology

    1 answer

    1. There is no PERLS stain testing performed on this product and a Biological Stain Commission-qualified Ferrocyanide product is not available. There is no reason to suspect that the P3289 would not be suitable at a minimum purity of 98.5 %. However, the Reagent Plus product option, P9387, is the starting material used in our HT20 Iron Stain kit. This product may be the best option. In addition, the HT20 Iron Stain kit is also suitable for PERLS staining. Please see the links below to review each of these products:
