Descripción general

El dimetil sulfóxido es un organosulfurado, comúnmente utilizado como disolvente polar que puede disolver una amplia variedad de compuestos polares y no polares. También se utiliza como reactivo de reacción en varios procesos bien conocidos, como la oxidación de Swern, la oxidación 2a de Pfitzner-Moffatt, 2b y la reacción de Corey-Chaykovsky [1] [2]

Aplicación

El dimetil sulfóxido (DMSO) se ha utilizado:
  • en la preparación de etil 4-[18F]fluorobenzoato.[3]
  • en el medio de cultivo para el ensayo del bromuro del 3-(4,5-dimetiltiazol-2-il)-2,5-difenil-tetrazolio (MTT).[4]
  • como disolvente en síntesis química.
  • para disolver y preparar disoluciones madre de moléculas pequeñas, fármacos y compuestos químicos para diversos ensayos y experimentos.

Precaución

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.

Questions

1–10 of 11 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/449/386/product-dating-information-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

  3. I know that this substance is of 2 types, with smell and without smell. What type is this?

    1 answer
    1. This is a high purity DMSO. While odor is not a tested specification, high purity products are expected to be odorless. A disagreeable odor is due to the sulfur moiety in the material. DMSO may also contain small amounts of un-reacted Dimethyl Sulfide (DMS). This DMS is generally contributes to a disagreeable odor.

  9. Dimethyl sulfoxide (DMSO) should be a liquid.  Why did it arrive as a solid?

    1 answer
    1. DMSO supercools easily, and re-melts slowly at room temperature. The melting point is 16-19 °C. The solidified product can be re-liquefied by warming to room temperature without detriment to the product.

  10. What is the molarity of DMSO?

    1 answer
    1. DMSO will have a molarity of 14.1M, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.
