一般說明

氧化氘（D2O）又称重水，是一种氘化水。在D/H交换反应中，它是安全且廉价的氘（D）来源。[1] 氢（H）和D2O分子之间氘交换的平衡常数已经确定。[2] 研究表明在D2O中制备的明胶凝胶表现出比在水中制备的凝胶更高的刚性。[3] 温度对结晶和液态氘热容量的影响已有研究，并且其熔点、焓和熔化熵已经测定。[4] 其作为治疗人胰腺癌的潜在治疗剂的用途已有研究。[5]

應用

氧化氘可用于以下过程：
  • 作为NMR溶剂。[6]
  • β-氘代醇的制备。[1]
  • 用于在原子反应堆中吸附中子。[4]
  • 用作与六甲基二硅烷结合的氘转移剂，用于从炔烃制备1,2-二氘代二烯烃。[7]

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/449/386/product-dating-information-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
