Allgemeine Beschreibung

N, N-Dimethylformamide (DMF) is an organic compound commonly used as a reagent as well as a solvent in organic synthesis. It plays multiple roles in various reactions such as formylating agent, dehydrating agent, reducing agent as well as a catalyst.

Anwendung

Lösungsmittel für viele hydrophobe, organische Verbindungen.
DMF can be used as:     
  • A formylating agent for organometallic compounds.
  • A reactant to prepare Vilsmeier reagent by reacting with phosphorus oxychloride.
  • A reagent for amination of aryl chlorides in the presence of potassium t-butoxide.     
  • A reducing agent for metal salts to prepare metal colloids.
  • A catalyst for the regioselective silylation of unprotected carbohydrates.

DMF can also be used in the following:     
  • DMF-Phosgene catalytic system is used to prepare alkyl halides from alcohols.      
  • DMF-POCl3 is used to convert acyclic and cyclic enolizable ketones to β-chloro-α, β-unsaturated aldehydes.
  • DMF-POCl3 is used to synthesize quinoline-3-carbaldehydes from acylanilides.      
  • DMF-SOCl2 combination is used to dehydrate oximes to nitriles.      
  • DMF-Ag2O converts α-bromopropionamides to oxazolidinones.
  • DMF is frequently used as a solvent in many chemical reactions, which require a high solvency power.

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
