Description générale

Acetic acid-d4 (Tetradeuteroacetic acid), a deuterated carboxylic acid,[1] is the tetradeuterated form of acetic acid. Its dissociation constant has been evaluated in deuterium oxide (D2O) by an emf method.[2]

Application

Acetic acid-d4 has been used as a deuterated solvent for the dissolution of internal standard in qNMR (Quantitative Nuclear Magnetic Resonance) quantification experiments.[2]
Acetic acid-d4 may also be used as a deuterated solvent in the 1H NMR spectral studies of the following:
  • CB2, a CNBr peptide[3]
  • α - tocopherol succinate hydrophobically modified chitosan(CS-TOS)[4]

Along with decarbamoylsaxitoxin and decarbamoylgonyautoxin-2 and -3, six new saxitoxin analogues were isolated from the freshwater mat-forming filamentous cyanobacterium Lyngbya wollei collected from Guntersville Reservoir on the Tennessee River in Alabama. Their structures were determined by electrospray ionization mass spectrometry

Questions

1–2 sur 2 questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse

    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.

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

    1 réponse

    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
