Application
Le DMSO a été utilisé comme milieu pour préparer un réactif de chimioluminescence de substitution à un kit du commerce de chimioluminescence améliorée employé dans la technique d′immunoblotting.[1]
Biochem/physiol Actions
Le DMSO est une substance fortement polaire qui peut être utilisée comme solvant industriel pour les composés chimiques organiques et inorganiques. Il est également employé comme agent protecteur lors de la cryoconservation des cellules vivantes.[2][3] Il est également utile dans l′oxydation des thiols et des disulfures en acide sulfonique.[4]
Disclaimer

How can I determine the shelf life / expiration / retest date of this product?
1 réponse-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 réponse-
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

Is the DMSO (Dimethyl Sulfoxide) still considered usable if it was received in a frozen or solid form?
1 réponse-
Yes, DMSO (Dimethyl Sulfoxide) is still considered usable even if it was received in a frozen or solid form. The solidified DMSO can be easily re-liquefied by warming it to room temperature.

My application requires a dry solvent. How can I remove water that is present in Dimethyl sulfoxide, Product D5879?
1 réponse-
This product has a water content specification of not more than 0.1%, which may be low enough for your application. Other DMSO products may have more water present. Molecular sieves are typically zeolite compounds that strongly adsorb water and have carefully controlled pore sizes. If you would like, dried sieves may be placed into the bulk solvent container (about 5%-10% by volume) to remove most water. Sigma-Aldrich offers 4 Å molecular sieves (e.g. product 334308), which would be effective in removing residual water from DMSO.

The Dimethyl sulfoxide, Product D5879, I ordered arrived as a solid. Is the product still acceptable?
1 réponse-
Sigma-Aldrich ships many products, including DMSO, at ambient temperature. As a result product D5879 might arrive as a solid depending on the weather conditions during shipment. The melting point of DMSO is 16-19°C. Therefore, if the solid is allowed to warm to room temperature, it will melt without any impact on the quality of the product.

What is the molarity of Product D5879, Dimethyl sulfoxide?
1 réponse-
Pure solvents do not technically have a molarity (defined as moles of solute per liter of solution), since there is no solute distinct from the pure material. However, an effective molar concentration of 14.1M can be determined for this product, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.
