General description

Manganese(II) acetate tetrahydrate is an ionic compound soluble in water and polar solvents. It is commonly used as a precursor in chemical vapor deposition processes to fabricate cathode materials for lithium-ion batteries. It is also used as a sol-gel precursor to synthesize manganese oxide-based catalysts and other functional materials. Additionally, manganese(II) acetate tetrahydrate serves as a mordant in dyeing, a drier for paints and varnishes, and an oxidation catalyst. It is employed in the production of high-purity manganese dioxide, manganese oxide hydrate, and other manganese-containing compounds.

Application

Manganese(ll) acetate tetrahydrate can be used as:     
  • A starting material in the synthesis of manganese carboxylates, which are used to prepare manganese oxide thin films by chemical vapor deposition (CVD).     
  • A precursor in the synthesis of manganese-TiO2 composites by chemical vapor condensation (CVC).These composites are used in the oxidation of NO at low temperatures.     
  • A precursor in preparation of NCM (LiNi1/3Co1/3Mn1/3O2) powder applicable as cathode material in lithium-ion batteries.     
  • A starting material for the synthesis of LiMn2O4 (LMO) film on Au substrate by sol-gel method.

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
