一般說明

2-甲基-2-丁醇是戊醇的异构形式。2-甲基-2-丁醇的各种物理性质（静电介电常数、粘度、密度、超声波和介电弛豫）已经在很宽的温度范围内进行了评估。[1]其作为溶剂，从水溶液中萃取糠醛的能力已经得到了测试。[2]在不存在溶剂的情况下，由市售钯基催化剂催化的MBY与氢的三相反应的动力学参数也已有描述。[3]

應用

2-甲基-2-丁醇（叔-戊醇， t-AmylOH，MBY）已被用作溶解阿佛丁[2,2,2-三溴乙醇]的溶剂，[4] 阿佛丁可在免疫组织化学研究中用作麻醉剂。[5]它已被用于制备（E）-2-（2-（3-乙氧基-3-氧代丙-1-烯基）-6-氟苯基）乙酸。[6]

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
