Descripción general

tert-Butylamine (TBA) is an aliphatic primary amine. Its enthalpy of combustion and formation has been studied.[1] Its gas phase acidity[2] and gas phase basicity has been evaluated.[3] The ozonation of tert-butylamine has been reported.[4] Its influence on the aqueous beta-cyclodextrin (β-CD): pyrene complex has been examined by steady-state fluorescence measurements.[5]

Aplicación

tert-Butylamine (t-butylamine) may be used in the synthesis of Zn2-SnO4 nanoparticles.[6] It may be used to terminate the polymerization reaction during the synthesis of the following polymers (DAB =1,4-diaminobutane, BA=Boronic acid , PAA=functional poly(amido amine), ABOL=4-aminobutanol, Bn=Benzyl):[7]
  • (DAB-BA-PAA)
  • (ABOL-BA-PAA)
  • (DAB-Bn-PAA)
tert-Butylamine (TBA) is suitable for use as an indicator molecule in the study of NMR-based pH determination method, free of glass electrode errors in highly basic media.[8] It is suitable for use in the synthesis of methyl β-ketophosphonate[9], titanium dioxide nanoparticles (TiO2 NPs)[10][11] and samarium oxide (Sm2O3) nanospheres and nanorods.[12] It may be used in the following studies:
  • As liquid hydrocarbon promoter in the systematic study on methane hydrate formation and dissociation.[13]
  • As an example in the study of the effect of amines in influencing atmospheric H2SO4-H2O nucleation.[14]
  • Hydroamination of terminal alkynes.[15]
  • To measure the surface acidity of solid catalysts by temperature-programmed desorption.[16]
  • As a reductive nitrogen source in the atomic layer deposition technique used to deposit TaN thin films from TaCl5 and TaBr5.[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 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
