Trifluoroacetic acid (TFA) is an organofluorine compound used as a reagent in organic synthesis for various acid-catalyzed reactions such as ring-opening of epoxides, biomimetic cyclization, Cope rearrangements, and natural product synthesis. TFA′s physicochemical characteristics provide advantages over other acids because of its high volatility, solubility in organic solvents, and acidic strength. When TFA is used as a reagent the product isolation is simple by evaporation due to its very high volatility. Less volatile acids such as sulfuric acid or p-toluenesulfonic acid may require neutralization or an extractive workup.

Application

Trifluoroacetic acid can be used as a reagent:      
  • For the cleavage of nitrogen and oxygen protecting groups such as N-Boc, N-benzyloxymethyl, benzyl ether, p-methoxybenzyl ether, t-butyl ether, t-butyloxymethyl ether, triphenylmethyl ether, and dimethyl acetals.      
  • In the Baeyer–Villiger oxidation reactions in combination with sodium percarbonate.,·      
  • For the C-H trifluoromethylation of arenes.

TFA can also be used as:      
  • A solvent in atom transfer cyclization reactions and polymer processes.      
  • A catalyst in the synthesis of ε-caprolactam via Beckmann rearrangement of cyclohexanone oxime in aprotic solvents.

Packaging

1mL in each ampule.

Questions

1–3 of 3 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/418/501/product-dating-information-06-25-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
