Descripción general

Divinyl sulfone is a highly reactive chemical compound due to the presence of two vinyl groups, which make it an effective cross-linking agent and bifunctional reactive compound. It is used in the production of hydrogels, resins, and other polymeric materials. The resulting cross-linked polymers exhibit enhanced mechanical strength, stability, and insolubility in solvents.

Aplicación

Divinyl sulfone can be used as:
  • A cross-linking agent to synthesize divinyl sulfone-crosslinked hyaluronic acid hydrogels for specific biomedical applications, such as tissue engineering or drug delivery.
  • A cross-linking agent to develop the conducting polymer film with MXene layers. This crosslinking can enhance the mechanical properties and stability of the composite film.
Hyaluronic acid (HA) crosslinked with DVS forms hydrogels.
DVS and its mono and di-substituted derivatives are useful starting materials in the preparation of thiomorpholine 1,1-dioxides and other synthetically important macro- and the heterocycles.
DVS may be used to shrink proofing cotton by crosslinking it with cellulose.

An unprecedented intermolecular iminium/enamine Michael addition on enals has been developed by taking advantage of the high reactivity of vinyl sulfones. This powerful organocascade allows for the rapid construction of attractive synthons in high enantioselectivities (typically 99% ee).

A new, selective method for the synthesis of (E)-vinyl sulfones is presence by palladium-catalyzed C-S bond cleavage/conjugate addition. In the presence of Pd(OAc)(2) and DMEDA (N(1),N(2)-dimethylethane-1,2-diamine), 1,2-bis(phenylsulfonyl)ethane underwent the C-S bond cleavage, followed by conjugate addition to numerous electron-deficient alkynes

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
