Opis ogólny

Hexafluoroisopropanol (HFP) is generally used to denature the native state of proteins, and it also stabilizes the a-helical conformation in unfolded peptides and proteins like ß-lactoglobulin and melittin.[1]

Zastosowanie

Suitable for the derivatization of glutamic acid, homovanillic, iso-homovanillic and dihydroxyphenyl acetic acids and Υ-aminobutyric acid.

Inne uwagi

Reagent for hexafluoroisopropyl ester, N-pentafluoropropionyl, and trifluoroacetyl..

We demonstrate a novel in situ polymerization technique to develop localized polymer coatings on the surface of dispersed pristine graphene sheets. Graphene sheets show great promise as strong, conductive fillers in polymer nanocomposites; however, difficulties in dispersion quality and interfacial

Small molecule cholinesterases inhibitor (ChEI) provides an effective therapeutic strategy to treat Alzheimer's disease (AD). Currently, the discovery of new ChEI with multi-target effect is still of great importance. Herein, we report the synthesis, structure-activity relationship study and biological evaluation

1,1,1,3,3,3-Hexafluoroisopropanol is re-examined as an eluent for size-exclusion chromatography (SEC) of polyesters, nylons, and other polar polymers. It is shown that anomalous SEC behavior reported in previous literature can be eliminated by adding 0.01 M tetraethylammonium nitrate to the eluent.

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.
