Description générale

N,N-Dimethylformamide (DMF) is a polar organic solvent with a wide range of industrial applications.[1] It is a precursor for numerous reactions such as formylation, aminocarbonylation, amination, amidation and cyanation.[2] Along with phosphorus oxychloride, it forms Vilsmeier reagent used in the formylation of reactive aromatic and heteroaromatic substrates.[3] Dielectric relaxation experiments on DMF have been conducted between 238.15 K and 338.15K.[4] The thermophysical properties of the molecular interactions between DMF and the ionic liquids, ammonium salts and imidazolium salts have been studied.[5] The characteristics of solute-solvent interactions between ammonium nitrate and DMF have been investigated.[6]

Application

Solvant pour de nombreux composés organiques hydrophobes
N,N-Dimethylformamide has been used in the to prepare pure polyurethane as well as nanocomposite solutions.
It may be used in the following processes:
  • Synthesis of gold nanoparticles.[7]
  • Capillary electrophoresis.[8]
  • Regioselective synthesis of N,N-dimethylaminopyridzines.[9]
  • Synthesis of urea-N,N-dimethylformamide, a 3:1 solvate with urea.[10]

Autres remarques

A Greener alternative is available for many DMF applications, Cyrene (807796)

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
