一般描述

对二甲氨基苯甲醛（4-二甲氨基苯甲醛）是含氨基和醛基的羰基有机物。可用作Ehrlich and Kovac′s吲哚检测试剂组分。对二甲氨基苯甲醛可用于通过Grignard格氏试剂制备醛类物质。此外，也可用作吡咯、伯胺和肼检测的显色试剂。[1]

应用

4-二甲氨基苯甲醛可用于几丁质酶分析[2]。

4-二甲氨基苯甲醛的用途：
  • 用于缩合反应合成偶氮-甲亚胺染料。[3]
  • 作为试剂与4-硝基苯酚反应合成分子加合物4DMAB4NP（4-二甲氨基苯甲醛4-硝基苯酚）。[4]
  • 席夫碱制备。[5]
与吡咯和伯胺反应生成有色缩合产物(席夫碱)。

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
