一般描述

DBN是一种强碱，广泛用作有机合成中的催化剂，可促进迈克尔加成和羟醛缩合。[1][2][3]

应用

1,5-二氮杂二环[4.3.0]壬-5-烯（DBN）可以用作：      
  •   通过脱氢/脱羧芳构化将四氢-β-咔啉合成为β-咔啉的一种试剂[4]       
  • 通过Friedel−Crafts酰化反应进行的吡咯和吲哚的区域选择性C-酰化中的亲核有机催化剂。[1]
  •   三元液相-液相变化系统配方中的超强碱，并与十六烷和己醇一起用于捕获硫化氢气体。[5]      
  • 使用超临界二氧化碳作为反应物和溶剂，由2-氨基苄腈制备1H-喹唑啉-2,4-二酮的一种碱。[6]
  •   2-氨基硫酚与CO2通过C-S键形成的环羰基化反应合成苯并噻唑酮的催化剂[2]

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
