General description

Zinc acetate is primarily utilized as a precursor or catalyst in various synthetic reactions. In organic chemistry, zinc acetate finds application as a reagent in the formation of carbon-carbon bonds. It can facilitate the synthesis of esters, allylic alcohols, and acetals. For example, it can promote the acylation of alcohols, phenols, and amines to form esters, such as the Fischer esterification reaction. Zinc acetate has also been used in the synthesis of metal-organic frameworks (MOFs). MOFs are porous materials consisting of metal ions or clusters coordinated to organic ligands. Zinc acetate can act as a precursor for the formation of MOFs due to its ability to coordinate with organic linkers and form robust networks.

For small scale and high throughput uses, product is also available as ChemBeads (927805)

Application

Zinc acetate has been used in:
  • Synthesis of layered Zn-arylphosphonates with potential application in sorption, ion exchange or catalysis.[1]
  • Ultrasonic preparation of zinc sulfide nanoparticles coated on silica particles.[2]
  • Synthesis of ZnO/ZnS composites throughion exchange method (1)
  • Fabrication of 3D hierarchical ZnO/ZnSheterojunction branched nanowires for enhanced photoelectrochemical watersplitting (2)
  • Synthesis of Co3O4-decorated ZnO@ZnS core-shellstructures for efficient photocatalytic overall water splitting (3)
  • Synthesis of ZnO photocatalysts (4)

Preparation Note

Preparation of ZnSe nanostructures upon thermolysis of zinc acetate and selenourea in a mixture of octadecylamine and trioctylphosphine oxide.[3]

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
