General description

Iron(III) chloride is brownish to black crystalline solid that is highly soluble in water. As a moderately strong Lewis acid, FeCl3 can form complex compounds and adducts with Lewis bases, making it a useful catalyst in various chemical reactions.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Iron(III) chloride can be used:
  • As a precursor to prepare Fe(III)-chlorophyll complex. Fe(III) enhances the performance of chlorophyll as a dye sensitizer in DSSCs by forming complex compounds with metal-ligand charge transfer properties, leading to increased efficiency and improved paramagnetic properties.
  • As a catalyst /modifying agent to prepare high performance porous carbon for lithium-ion battery anodes. The addition of FeCl3 enhances the graphitization of porous carbon without significantly affecting the layer spacing and also the specific surface area and pore volume of porous carbon.
  • As a co-catalyst to fabricate liquid catalyzed fuel cell (LCFC) for direct conversion from carbohydrates to electricity. It helps to improve the hydrolysis of carbohydrate and enhances the electron transfer from carbohydrates to anode.

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resitance properties.

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
