一般描述

1,3-二恶烷是一种杂环乙缩醛，常用作制剂和生产工艺中的绿色溶剂。它还可用作有机合成中的反应物。1,3-二恶烷的长期储存会形成有机过氧化物。可通过添加丁基羟基甲苯(BHT)作为稳定剂而抑制这一过程。BHT能去除形成过氧化物所需的自由基。

应用

1,3-二恶烷可用作以下反应的溶剂：      
  • 从生物质中提取可生物降解的聚(3-羟基丁酸)（PHB）。     
  • 生产稳定的多壁碳纳米管(MWCNT)分散液用于合成修饰玻璃碳电极。
  • 在maghnite-H+ 催化剂存在的情况下通过1;3;5-三恶烷的阳离子共聚反应合成共聚物（聚氧亚甲基）。

它也可作为反应物用于通过Sc(OTf)3催化的开环聚合反应制备准固态聚1,3-二恶烷电极。

An efficient synthesis of the angiotensin II receptor antagonist telmisartan is presented involving a decarboxylative cross-coupling of isopropyl phthalate (1) with 2-(4-chlorophenyl)-1,3-dioxolane (2c) as the key step (85% yield). The benzimidazole moiety is constructed regioselectively via a reductive amination-condensation sequence

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
