Általános leírás

Sodium trifluoromethanesulfonate (Sodium triflate or NaOTf) is an efficient catalyst as well as a reagent in many organic reactions. The prominent application includes catalytic asymmetric Mannich-type reactions, Mannich-type reactions in water, and Diels-Alder reactions.[1]It is also used as an electrolyte in batteries.[2]

Alkalmazás

Sodium trifluoromethanesulfonate can be employed as a reagent for the preparation of:
  • Aryl fluorides via silver-catalyzed fluorination of arylstannanes.[3]
  • Ionic liquids such as N, N -dialkylpyrrolidinium triflate, N,N-dialkylimidazolium triflate, and N-alkylpyridinium triflate.[1]

It can be also used as supporting electrolyte in electrochemical O-glycosylation of primary alcohols with O-protected thioglycosides.[4]

High theoretical capacity and low-cost copper sulfide (CuxS)-based anodes have gained great attention for advanced sodium-ion batteries (SIBs). However, their practical application may be hindered due to their unstable cycling performance and problems with the dissolution of sodium sulfides (NaxS)

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.
