一般說明

苊是一种多环芳烃，常用作合成聚合物和树脂的合成砌块。[1][1][1]
Beijerinckia sp.和Beijerinckia sp.菌株B8/36对苊的细菌氧化作用已有报道[2]。苊通过与β-环糊精和醇的包合物络合形成1:1:1的包合物[3]。已在296 ± 2K条件下研究了苊与NO3自由基、O3和N2O5等的气相反应动力学[4]。

應用


  • 苊的生产优化：一篇研究文章介绍了在2100 bar下进行浆料填充制备的高效HILIC毛细管柱的应用，展示了一种先进的技术，可以优化苊等复杂多环芳烃的合成和纯化，这对提高化学工艺的生产率和纯度至关重要（Anderson et al., 2024）。

  • 环境影响评估：一项研究考察了PM2.5排放中多环芳烃（PAH）与活性氧之间的关系，对工业地区苊等化合物对环境的影响进行了批判性评估，从而为污染控制和环境安全策略提供参考（Xu et al., 2024）。

  • 有机半导体材料的研究进展：研究重点是芘桥联苊的合成和性质，有助于开发新型有机半导体材料，这对电子和光子应用至关重要，从而拓宽苊在高科技产业中的应用（Polkaehn et al., 2023）。

  • 有机污染物的生物测定：研究人员使用基于化学活性的人工沉积物负载开发了苊等有机污染物的生物测定法。这种方法提出了一种评估有机污染物相关生态风险的新方法，同时还优化了多环芳烃预测无影响浓度（PNEC）的推导，这对监管合规性和环境健康至关重要。（Abel et al., 2024），（Sun et al., 2023）。

A Beijerinckia sp. and a mutant strain, Beijerinckia sp. strain B8/36, were shown to cooxidize the polycyclic aromatic hydrocarbons acenaphthene and acenaphthylene. Both organisms oxidized acenaphthene to the same spectrum of metabolites, which included 1-acenaphthenol, 1-acenaphthenone, 1,2-acenaphthenediol, acenaphthenequinone, and a

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/449/386/product-dating-information-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
