應用

这种固体氟磺酰基咪唑鎓三氟甲磺酸盐,SuFEx-IT,是硫酰氟(SO2F2)的方便替代品,硫酰氟是一种有害的熏蒸胀气,处理程序困难,使SO2F2及其能够生产的产品难以访问。但是,该试剂具有新颖的反应性、选择性和范围,并且由K.Barry Sharpless和Jiajia Dong的实验室证明可以将酚、伯胺和仲胺转化为氟硫酸盐和氨磺酰氟。氟硫酸盐广泛用于生物学研究,药物化学中,并在Pd催化的交叉偶联反应中用作假卤化物。
在4 °C的干燥环境下保存(建议使用干燥器)。

使用Synple自动合成平台(SYNPLE-SC002)自动进行氟化反应。

Sulfuryl fluoride, SO2 F2 , has been found to derivatize phenols in all kinds of environments, even those in highly functional molecules. We now report that a solid fluorosulfuryl imidazolium triflate salt delivers the same "F-SO2 +" fragment to Nu-H

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
