一般說明

其产物为己烷异构体和甲基环戊烷的混合物。可以通过蒸馏或裂解的方法从石油中分离出己烷(异构体的混合物)。它们构成石油醚的主要成分。它是一种不可再生的有机溶剂,主要用于油脂的溶解和提取。[1] 使用Fe2(BDP)3(BDP2- = 1,4-苯二吡唑酸酯)根据支化度对己烷的异构体进行分离的研究已有报道。[2]

應用

己烷 (n-己烷)已用于制备手性固定相 (IMPCSP) 合成所需的前体。通过高效液相色谱 (HPLC) 和超临界流体色谱 (SFC),IMPCSP 可用于外消旋药物的对映体分离。[3]其可用作微流体装置的载体相。[4]

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
