一般描述

环氧氯丙烷 (ECH) 是一种无色、易挥发、高反应活性的有机化合物,是生产甘油、塑料、药物和油漆的前驱体。[1][2]
这种物质被列入EU第10/2011号法规中用于与食品接触的塑料的正面清单。请点击此处查看列入10/2011 的所有化合物的参考物质。

应用

ECH 已被用作参比标准品,通过选择离子监测 (SIM) 模式下的环氧乙烷衍生化和气相色谱-质谱 (GC-MS) 鉴别环氧乙烷涂层罐头中的 ECH,[2]并通过静态顶空 (HS) 和吹扫捕集器(P&T)与配备有电子捕获检测器 (GC-ECD) 的 GC 联用。[3]
其可作为引用色谱法分析饮用水中 (±)-ECH 的参考标准 [4],以及 HS-固相微萃取 (HS-SPME) 结合 GC-火焰离子化检测器 (GC-FID) 和 GC-ECD 分析污水处理厂出水中的 (±)-ECH 的参考标准。[1]

The diverse biological effects of xenoestrogens may be explained by their ability to differentially recruit co-regulatory proteins to the estrogen receptor (ER). We employed high-throughput receptor affinity binding and co-regulatory protein recruitment screening assays based on fluorescence polarization and time

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
