一般說明

二甲基亚砜-d6(DMSO-d6)是氘代溶剂。[1]它是 100% 同位素富集的 NMR(核磁共振)溶剂。由于化学和同位素纯度高,它被广泛用于高分辨率 NMR 研究。在 193 和 222nm 范围内的光照射下,它经过分解产生 CD3 自由基。已经通过红外二极管激光吸收光谱法评估了 CD3 的量子产率。[2]100% DMSO-d6 在远程 COSY(相关光谱)实验中已用作溶剂。[3]

應用

二甲基亚砜-d6 已用作其质子、13C(碳-13)和 2D NMR(二维核磁共振)光谱研究期间葡聚糖溶解的溶剂。[4]二甲基亚砜-d6 可用作溶剂以研究相应的 1,3-苯并恶嗪和 1,3-苯并恶嗪酮的核磁共振谱(NMR),其倾向于具有抗微生物活性。[5]

Questions

1–4 of 4 Questions  
  1. Hello, what is the molarity of DMSO-d6 (156914)?

    1 answer
    1. The concentration of this product can be determined using the lot-specific purity reported in the Certificate of Analysis, the density, and the compound's molecular weight. This product has a density of 1.190 g/mL and a molecular weight of 84.17 g/mol. The minimum purity is 99.0%, thus the molarity will vary slightly from lot to lot. The molarity can range from 13.9 M (99.0%) to 14.1 M (100%).

  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

  3. 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
