一般說明

三乙胺(TEA, Et3N)是一种脂肪族胺。将它添加到基质辅助激光解吸/电离（MALDI）基质中，可在MALDI质谱（MS）成像过程中为透明的液体基质提供增强的空间分辨能力。[1]一种用于测定活性药物成分中的三乙胺的顶空气相色谱（GC）过程已被报道。[2]在一定密度和温度范围内三乙胺蒸汽的粘度系数已得到测量。[3]

應用

三乙胺已用于以下合成过程：
  • 5′-二甲氧基三苯甲基-5-（呋喃-2-基）-2′-脱氧尿苷[4]
  • 3′-（2-氰乙基）二异丙基-5′-二甲氧基三苯甲基-5-（呋喃-2-基）-2'-脱氧尿苷[4]
  • 聚乙胺600-β-环糊精（PEI600-β-CyD）[5]
它还可通过甘油和碳酸二甲酯（DMC）之间的酯交换反应用作制备二碳酸甘油酯的均相催化剂。[6]

Questions

1–4 of 4 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

  3. Hello, I would like to know the molarity of this product Triethylamine 471283-100ML and in what it is? I tried to read it this information on the picture but it’s too small and not clear… Thank you for your help!

    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 molecular weight. This product has a density of 0.726 g/mL and a molecular weight of 101.19 g/mol. The minimum purity is 99.5%, thus the molarity will vary slightly from lot to lot. The molarity can range from 7.14M (99.5%) to 7.17M (100%).
