General description

La N, N-dimetilformamida (DMF) es el disolvente comúnmente empleado para las reacciones químicas. La DMF es un disolvente útil empleado para el aislamiento de la clorofila de los tejidos vegetales.[1] Es un reactivo ampliamente utilizado en síntesis orgánica. Desempeña múltiples papeles en varias reacciones, como disolvente, como deshidratante, como reductor y como catalizador. Es una unidad estructural multifunción para la síntesis de compuestos que contengan O, -CO, -NMe2, -CONMe2, -Me, -CHO como grupos funcionales.[2]
La N,N-dimetilformamida es un disolvente polar que se utiliza comúnmente en la síntesis orgánica. También actúa como precursor multipropósito para las reacciones de formilación, aminación, aminocarbonilación, amidación y cianación.[2]

Application

La N,N-dimetilformamida (anhidra) se ha utilizado como disolvente para la síntesis del conjugado citotóxico de hormona liberadora de la hormona luteinizante (LH-RH) AN-152 (un quimioterápico) y el fluoróforo C625 [4-(N,N-difenilamino)-4′-(6-O-hemiglutarato)hexilsulfinil estilbeno].[3] Puede utilizarse como medio disolvente para las diversas reacciones de reducción orgánica.[4]
El DMF se ha utilizado como disolvente en los siguientes procesos:
  • La síntesis en varios pasos de la L-acidohomoalanina (L-Aha) durante la sustitución del mesilato por acida sódica.[5]
  • La síntesis de fosfina-FLAG®, un reactivo de detección para el marcaje metabólico de los glucanos.[6]
  • La síntesis de 6-acidofucosa per-O-acetilada, un azúcar ácido per-O-acetilado.[6]
Disolvente para muchos compuestos orgánicos hidrófobos.

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.

  3. What is the shelf-life of this product at room temperature? Unopened and opened?

    1 answer
    1. This product is not assigned an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one-year warranty from the date of shipment.

      For more information, you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/life-science/quality-and-regulatory-management/quality-services.

      The shelf life of the product after opening has not been investigated and would depend on environmental and handling factors such as humidity and contamination.
