一般描述

2-溴丁烷和丁醇的异构形式的二元混合物的粘度，已经在298.15和313.15K条件下进行了评估。[1] 其在与分子溴反应期间，2,2-二溴丁烷、赤-2,3-二溴丁烷和dl-2,3-二溴丁烷 作为主要的光致溴化反应产物形成。在该反应中也会获得较小产率的1,2-二溴丁烷和2,2,3-三溴丁烷。[2]
2-溴丁烷是一种烷基卤。已报道在镍-铝合金存在下，可在氢氧化钾溶液中通过还原脱卤作用对2-溴丁烷进行降解。[3] 通过气相色谱法测定烷基溴化物混合物中的2-溴丁烷已有报道。[4] 2-溴丁烷在KOH-二氧化硅上的脱溴化氢反应的立体化学已有研究。[5]

应用

2-溴丁烷可用于合成一系列非核苷。[6]

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
