Allgemeine Beschreibung

Zinc acetate dehydrate is an organic zinc salt. Its enthalpy of formation has been studied using solution calorimetry.[1] Its vibrational spectra has been analyzed.[2] It decomposes into ZnO (zinc oxide) nanoparticles which has been investigated using time-of-flight secondary ion mass spectrometry (TOF-SIMS).[3] A study on the crystalline structure has revealed that it is monoclinic with space group C2/c.[4]

Anwendung

Eingesetzt bei der Synthese von geschichteten Zn-Arylphosphonaten mit möglichen Anwendungen in der Sorption, Ionenaustausch oder in der Katalyse.[5] Angewendet auch in der Ultraschall-Herstellung von Zink-Sulfid Nanopartikeln auf Silica-Partikeln.[6]

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.

  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
