General description

乙醛是一种无色易燃的有机液体。它可以由乙炔水合和乙醇催化氧化产生。主要用于生产乙酸。
乙醛的热分解机理已有报道。[1]它是肝脏中的乙醇代谢产物,可与各种蛋白质共价结合,从而改变肝脏的功能和结构。[2]在水滑石型催化剂存在下的乙醛和庚醛的醇醛缩合已有所介绍。

Application

生物医学应用里,关于生产具有细胞粘合性和排斥性的纤维状生物材料的研究中,乙醛可用于在等离子体聚合中将反应性醛基沉积到基质上。在采用气相色谱-火焰离子化检测法(GC-FID)测定全血、玻璃状液、尿液等不同人体基质中的丙酮、乙醛、乙醇和甲醇时,也可将其用作校准标准品。
乙醛可用于酶促合成脂肪酸。[3]

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/418/501/product-dating-information-06-25-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
