General description

Iron(III) citrate technical grade is a brown to dark orangepowder. It is soluble in water, but insoluble in most organics includingalcohols. The powder is sensitive to light; like many iron carboxylates, bluelight photo-reduces iron(III) citrate, forming the Fe2+ ion andconcomitantly oxidizing the carboxyl group to yield carbon dioxide. Iron(III)citrate thermally decomposes to α-Fe2O3 at 460 °C.

Application

Iron(III) citrate is a synthetic precursor for iron-containing compounds. It is commonly used to prepare Fe3O4 nanoparticles or Fe3O4-nanocomposites by hydrothermal methods and Fe2O3 materials by thermal decomposition and sol-gel processing.[1] Iron(III) citrate is well-suited to sol-gel processing because of its high solubility in water and low solubility inorganic phases. Consequently, iron(III) citrate is an important precursor in the synthesis of iron-doped and iron-containing metal oxides studied for lithium-ion battery cathodes.[2]

It can also be used in the degradation of tetracycline for the treatment of polluted water.

Questions

1–2 of 2 Questions  

  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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
