甲胺(CH3NH2)是一种简单的脂肪族伯胺化合物，在有机合成中用作化学中间体。它主要用于生产农药和溶剂。[1][2]

應用

2.0M甲胺溶液（溶于THF）可用作促进钙钛矿型材料合成的前体。它还可作为失活剂用于研究大孔酸性离子交换树脂的催化性能。它可通过退火减少晶粒边界中的杂质，从而提高钙钛矿型太阳能电池的稳定性和效率。[3][4][5]
甲胺可用作以下合成中的试剂：     
  • 二乙二醇合成甲基吗啉。[1]       
  • 以酮胺为起始物，经过亚胺的形成，再通过镍催化的氢化作用合成N-甲基烷胺类化合物。[1]   
  • 与丙烯腈反应，再通过氢化作用合成N-甲基二丙烯三胺。[1]  
  • 氯乙醇在NaCNBH还原剂的存在下合成N-甲基羟基吡咯烷。[6]       
  • 与6,7-二氯-1,4-蒽醌反应合成2-(甲氨)-6,7-二氯-1,4-蒽醌。[7]

A convergent and stereoselective synthesis of 2,5-disubstituted 3-hydroxypyrrolidines has been developed that involves reductive annulation of β-iminochlorohydrins, which are readily available from β-ketochlorohydrins, and provides rapid access to a variety of 2,5-syn-pyrrolidines. Application of this process to the concise (three-step)

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.
