General description

Le diméthylsulfoxyde (DMSO) est un solvant aprotique efficace. C'est un produit incolore, inodore et hygroscopique. Le DMSO augmente la perméabilité de divers perméants hydrophiles et lipophiles. C'est l'un des solvants couramment utilisés dans le laboratoire.

Application

Le diméthylsulfoxyde (DMSO) a été utilisé comme véhicule de composés à tester dans diverses études expérimentales. Il a également été utilisé comme solvant dans le protocole d'agrégation de l'amyloïdeβ (Aβ) pour la resolubilisation du peptide en vue de maintenir son état dissocié.

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/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

  5. What type of filter is used to sterile-filter Dimethyl sulfoxide (DMSO)?

    1 answer
    1. DMSO can be sterile-filtered through a 0.2 micron PTFE filter. The sterility testing is per the current US Pharmacopoeia method.

      Helpful?

  6. What is the DMSO dissolved in?

    1 answer
    1. DMSO is not dissolved in any solvent. It is a pure chemical compound that is a liquid at room temperature.

      Helpful?

  7. Does DMSO have any synthetic utility?

    1 answer
    1. DMSO has been used to oxidize thiols and disulfides to sulfonic acids, hydrolysis of epoxides, thioalkylation of phenols, and oxidation of primary alcohols and halides, and esters of primary alcohols to aldehydes.

      Helpful?

  8. 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.

      Helpful?

  9. 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.

      Helpful?

  10. Is Dimethyl sulfoxide a sterile product?

    1 answer
    1. No, this product is not considered sterile.  Product Nos. D2560 and D2438 are sterile-filtered.
