一般描述

二丙胺是一种脂肪胺，常用作芴甲氧羰酰基(Fmoc)的脱保护剂。[1]因氮原子上的孤电子对赋予的亲核特性，它可有效参与亲核取代反应。[2]

应用

  • 烃的分离：含氮可切换溶剂（switchable solvent），包括二丙胺，可用于分离烃及其衍生物，这一点体现了该化合物′在溶剂应用中的多功能性（Liu et al., 2020）。
  • 微萃取技术：采用二丙胺基分散微固相萃取与可切换亲水溶剂来改善环境水样品中非甾体抗炎药的富集，体现了其在复杂样品制剂中的用途 (Di et al., 2020）。
  • 均相液-液微萃取：研究人员开发了一种用于甲基苯丙胺的GC-MS测定的pH辅助均相液液微萃取新方法，该方法以二丙胺为具有有可切换亲水性（switchable hydrophilicity）的溶剂，重点介绍了其在分析化学应用中的有效性（Shahvandi et al., 2018）。
  • 去除污染物：研究表明，使用沸石和粉状活性碳以及二丙胺可同时去除高氨含量水中的氨和N-亚硝胺前体，该研究突出了其在环境领域的应用（Xue et al., 2018）。
  • 纳米级合成：采用二丙胺和乙醇极性均衡（ethanol polarity equalization）以共模板合成（co-templating synthesis）方法生产高产率纳米级(Si)AlPO-41，体现了二丙胺在材料科学中的作用（Majano et al., 2015）。

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
