一般說明

三溴化磷(PBr3)通常用于Hell-Volhard-Zelinsky卤化,以对羧酸进行α-溴化,从而形成相应的酰基溴。它也可用于将伯醇和仲醇转化为烷基溴。[1]

應用

三溴化磷可用作如下反应的试剂:
  • 合成7-乙氧基-1-(-乙基苯氧基)-3,7-二甲基-2-辛烯(一种类似于反式反式顺式-10,11-环氧-7-乙基-3,11-二甲基三癸-2,6-二烯酸盐的合成保幼激素)的新实验方案。 [2]
  • 合成带有色酮环的1,2,3-二氮杂膦、1,2,3-噻唑膦和1,2-氮杂磷杂环戊烯。[3]
  • 从10-十一碳烯-1-醇合成1-溴代十一碳-1-烯。[4]

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.

  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
