一般說明

二乙胺（DEA）是一种有机碱[1] 和弱σ-供体配体。[2]

應用

二乙胺已被用于组成提取溶剂混合物，用于三聚氰胺和相关化合物的气相色谱-质谱（GC-MS）分析。它还被用作新型ELISA技术的断键剂，用于测定IgG抗PT（免疫球蛋白G抗百日咳毒素）抗体的亲合力指数（AI）。[3]
它可以用作：
  • 制备β-膦羧基丙二腈和二乙基（2-氨基-3-氰基-苯并吡喃-4-基）膦酸酯的有机催化剂。[1]
  • 合成(N-杂环卡宾)PdCl2(二乙胺)配合物的配体。[2]
  • 制备热稳定和水热稳定的SAPO-34（硅铝磷酸盐）分子筛的模板。[4]

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
