Allgemeine Beschreibung

1,4-Dioxane is a heterocyclic organic compound that is commonly used as a solvent in several chemical reactions. It is also used as a stabilizer in chlorinated solvents.

Anwendung

1,4-Dioxane can be used as:      
  • A solvent in the N-methylation of amines by reductive functionalization of CO2 in the presence of NaBH4 as the reducing reagent.      
  • An additive to synthesize 3-hydroxylisoindolin-1-ones via hydroxylhydrative aza-cyclization of 2-alkynylbenzamide.

A mixture of 1,4-dioxane/ethanol/formic acid solvent system can be used in the depolymerization of lignin to synthesize value-added phenolic monomers.

Fragen

1-2 von 2 Fragen  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 Antwort

    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 Antwort

    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
