Description générale

N,N-Dimethylformamide-d7 (DMF-d7) is a deuterated derivative of N,N-dimethylformamide. It has an isotopic purity of 99.5atom%D. It is a standard purity solvent suitable for routine NMR analyses (conducted at ambient temperatures where quality is less critical). It participates as a solvent to evaluate the solvation of 1.7molar solution of lithium chloride (LiCl) by pulsed neutron diffraction studies.[1] Quadrupole splittings and quadrupole coupling constants of DMF-d7 oriented in a nematic phase have been evaluated by deuteron magnetic resonance studies.[2] DMF-d7 is being considered as a potent anti-cancer drug.[3]

Application

N,N-Dimethylformamide-d7 may be used to study its metabolism in rats by 2H NMR spectroscopy.[4]

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
