一般描述

二乙烯基砜是一种高反应性的化合物，因为存在两个乙烯基基团，这使其成为有效的交联剂和双功能反应性化合物。它用于生产水凝胶、树脂和其他聚合物材料。所得交联聚合物表现出增强的机械强度、稳定性和在溶剂中的不溶性。

应用

二乙烯基砜可用作：
  • 一种交联剂，用于合成二乙烯基砜交联的透明质酸水凝胶，用于特定的生物医学应用，如组织工程或药物递送。
  • 一种交联剂，用于开发具有MXene层的导电聚合物膜。这种交联可以增强复合膜的机械性能和稳定性。
透明质酸（HA）与DVS交联形成水凝胶。
DVS及其单取代和二取代衍生物是制备硫代吗啉1,1-二氧化物和其他合成重要的大环和杂环的有用的原料。
DVS可通过与纤维素交联而用于防缩棉。

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).

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.
      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
