Applicazioni

This solid fluorosulfuryl imidazolium triflate salt, SuFEx-IT, is a convenient alternative to sulfuryl fluoride (SO2F2), which is a harmful fumigant gas with difficult handling procedures that make SO2F2 -- and the products it is capable of making -- difficult to access. However, this reagent possesses novel reactivity, selectivity, and scope and was demonstrated by the labs of K. Barry Sharpless and Jiajia Dong to convert phenols, primary amines, and secondary amines to fluorosulfates and sulfamoyl fluorides. Fluorosulfates are used widely in biological studies, medicinal chemistry, and work as a pseudohalide in Pd-catalysed cross-coupling reactions.
Store in dry environment (desiccator advised) at 4 °C.

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

1–2 di 2 domande  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 risposta
    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 risposta
    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.
