一般描述

叔 -丁胺 (TBA) 是一种脂肪族伯胺。对其燃烧焓和生成焓进行了研究。[1]测定了它的气相酸度 [2] 和气相碱度。[3] 叔 -丁胺的臭氧化反应已有报道。[4]其对水溶性 β-环糊精（β-CD）：芘复合物已通过稳态荧光测量进行了检查。[5]

应用

叔 -丁胺（ t -丁胺）可用于合成 Zn 2 -SnO 4 纳米颗粒。[6]可用于终止以下聚合物（DAB = 1,4-二氨基丁烷，BA = 硼酸，PAA = 功能性聚（氨基），ABOL = 4-氨基丁醇，Bn = 苄基）合成过程中的聚合反应：[7]
  • (DAB-BA-PAA)
  • (ABOL-BA-PAA)
  • (DAB-Bn-PAA)
叔-丁胺 (TBA) 适用于在强碱性介质中无玻璃电极误差的、基于 NMR 的 pH 测定方法研究中作为指示分子。[8]适用于合成甲基 β-酮磷 [9]、二氧化钛纳米颗粒 (TiO 2 NPs) [10] [11] 和氧化钐 (Sm 2 O 3 ) 纳米球和纳米棒。[12]可用于以下研究：
  • 在甲烷水合物形成和分解的系统研究中作为液态烃促进剂。[13]
  • 作为研究胺影响大气 H 2 SO 4 -H 2 O 成核的例子。[14]
  • 末端炔烃的氢化反应。[15]
  • 用程序升温脱附法测定固体催化剂的表面酸性。[16]
  • 作为原子层沉积技术中的还原氮源，用于从 TaCl 5 和 TaBr 5 沉积 TaN 薄膜。[17]

The aminoacyl-beta-ketophosphonate-adenosines (aa-KPA) are stable analogs of the aminoacyl adenylates, which are high-energy intermediates in the formation of aminoacyl-tRNA catalyzed by aminoacyl-tRNA synthetases (aaRS). We have synthesized glutamyl-beta-ketophosphonate-adenosine (Glu-KPA) and glutaminyl-beta-ketophosphonate-adenosine (Gln-KPA), and have tested them as inhibitors of their

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
