應用

2-吡啶甲醛已用于：
  • 合成基于壳聚糖的双功能吸附剂。[1]
  • 在存在2-酮-3-脱氧-6-磷酸葡糖醛酸醛缩酶（KDPG）催化剂的条件下，与丙酮酸的醛醇缩合反应形成(S)-4-羟基-2-酮-4-(2′-吡啶基)丁酸酯。[2]
  • 与(S)-(−)-α-甲基苄胺和(R)-(+)-α-甲基苄胺的缩合反应,合成两个手性(S)-(−)-和(R)-(+)席夫碱化合物。[3]

此成分还可与硫代氨基脲结合形成2-吡啶甲醛甲醛硫代氨基甲酸酯配体(L)，从而进一步与Ni(II)和Cu(II)盐(MX)络合形成[M(L)2X2]复合物。[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
