General description

3-(Trimethylsilyl)-1-propanesulfonic acid sodium salt, also known as DSS sodium salt, is commonly used as an internal standard for referencing chemical shifts and scaling the intensity of all ¹H-NMR spectroscopy signals. [1]

Application

3-(Trimethylsilyl)-1-propanesulfonic acid sodium salt can be used as a reagent to synthesize polyamine block-copolymers. It can also be used as an internal standard in 1H NMR spectroscopy for the measurement of chemical shifts.

3-(Trimethylsilyl)propanesulfonic acid (TMSPS) is used as a water-soluble NMR frequency marker. It has its major resonance at 0.00 ppm relative to trimethylsilane, and smaller resonances at 0.62, 1.77 and 2.85 ppm. Its toxicity was tested by exposing contracted porcine carotid

The Alzheimer's Abeta40 peptide forms soluble oligomers that are extremely potent neurotoxins and strongly impede synapses function. In this study the formation and structure of the large, soluble, neurotoxic Abeta40 oligomer called "beta-ball" were characterized by two-dimensional NMR, circular dichroism

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
