General description

Manganese(III) acetate dihydrate is a coordination compound of manganese in the +3 oxidation state, exhibiting moderate solubility in water and acetic acid. It is used as a precursor for synthesizing manganese oxides and other manganese-containing materials. These materials have applications in batteries, catalysis, and other energy-related technologies. Additionally, it is also used as a mild and selective oxidizing agent in organic synthesis.

Application

Manganese(III) acetate dihydrate can be used as:      
  • A precursor in the synthesis of manganese oxide (Mn3O4) nanostructures, which are employed as anode materials in lithium-ion batteries.
  • A manganese source in the sol-gel synthesis of Mn-doped ZnO thin films. The incorporation of manganese ions into the ZnO lattice is essential for modifying the electronic and optical properties of the films.
  • A precursor for the synthesis of manganese oxide nanoparticles using a sol-gel process. These nanoparticles are evaluated for their performance in supercapacitor applications.     
  • A mild and selective oxidizing agent. Catalyzes allylic oxidation of a variety of alkenes in the presence of tert-butylhydroperoxide. Reagent used for radical cyclizations and α-keto-acetoxylation.

Physical form

Crystallographic evidence suggests this material is an oxo-centered triangle of Mn(III) with bridging acetates having the molecular formula: Mn3O(OAc)9 · 6H2O.

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
