General description

DMSO-d6是一种氘NMR溶剂,可用于基于NMR的研究和分析。

Application


  • 根据二甲亚砜溶液中的质子化学位移来估算肟的离解常数(pKa)。本研究利用二甲基亚砜-d₆(DMSO-d₇)来测定肟的pKa值,证明了其在提高质子核磁共振波谱在药物环境中化学分析和研究准确性方面的关键作用(Kurtz AP, D′Silva TD, 1987)。

  • 氨基酸的甲基硫代乙内酰脲、硫代乙内酰脲和氨基酸乙内酰脲的质子核磁共振研究:DMSO-d₆被广泛用于考察氨基酸研究中各种乙内酰脲衍生物的结构和行为,这对于理解蛋白质结构和功能至关重要,对学术和制药行业都有影响(Suzuki T, Tomioka T, Tuzimura K, 1977)。

Questions

1–2 of 2 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
