Allgemeine Beschreibung

1,4-Dibromobutane reaction with atactic poly(2-vinylpyridine) leads to the formation of long-range 3D molecular ordering in polymer chains[1].

Anwendung

1,4-Dibromobutane was used to investigate the metabolism of two halopropanes: 1,3-dichloropropane and 2,2-dichloropropane[2]. It was used as reagent during the synthesis of diazadioxa oxovanadium(IV) macrocyclic complexes[3].

Gemini Amphiphile-Based Lipoplexes for Efficient Gene Delivery: Synthesis, Formulation Development, Characterization, Gene Transfection, and Biodistribution Studies.

Mange R Yadav et al.

ACS omega, 3(9), 11802-11816 (2018-10-16)

Some quaternary gemini amphiphiles (GAs) were synthesized as nonviral gene delivery carriers. The critical miceller concentration values of these amphiphiles are indicative of their superior surface-active properties. All of the synthesized GAs, alone or along with lipids like cholesterol and/or

Biotransformation and quantitative determination of sulfur-containing metabolites of 1,4-dibromobutane in the rat.

W Onkenhout et al.

Drug metabolism and disposition: the biological fate of chemicals, 14(5), 608-612 (1986-09-01)

Two stable sulfur-containing metabolites were isolated from rat urine following administration of the mutagenic 1,4-dibromobutane. They were identified as tetrahydrothiophene and 3-hydroxysulfolane by gas chromatography and gas chromatography-mass spectrometry and were found to be excreted in 48-hr urine, representing 5.8

Fluorescence microscopy as an alternative to electron microscopy for microscale dispersion evaluation of organic-inorganic composites.

Weijiang Guan et al.

Nature communications, 7, 11811-11811 (2016-06-03)

Inorganic dispersion is of great importance for actual implementation of advanced properties of organic-inorganic composites. Currently, electron microscopy is the most conventional approach for observing dispersion of inorganic fillers from ultrathin sections of organic-inorganic composites at the nanoscale by professional

Template synthesis, spectroscopic characterization and preliminary insulin-mimetic activity of oxovanadium(IV) complexes with N₂O₂ diazadioxa macrocycles.

M L Sharma et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 95, 562-568 (2012-05-15)

A new series of diazadioxa oxovanadium(IV) macrocyclic complexes of type [VO(mac)]SO(4) have been synthesized via the condensation reaction of a 3-(phenyl/substituted phenyl)-4-amino-5-hydrazino-1,2,4-triazole (H(2)L) with salicylaldehyde/2-hydroxyacetophenone and 1,4-dibromobutane in the presence of oxovanadium(IV) sulfate in ethanol. All the newly synthesized compounds

[Study on the synthesis and spectra of 2-thenoyl-2-carbazolyl-N-butyltrifluoroacetone].

Qian Yu et al.

Guang pu xue yu guang pu fen xi = Guang pu, 24(2), 162-165 (2005-03-17)

In phene-50% NaOH medium, 1,4-dibromobutane reacts with carbazole (CZ) to form N-bromobutylcarbaole (BCZ) at 70-80 degrees C. The 2-thenoyl-2-carbazolyl-N-butyltrifluoroacetone (TCBTA) was synthesized by reaction of BCZ with 2-thenoyltrifluoroacetone (TTA) in acetone-K2CO3 medium at 50 degrees C. The TCBTA is a

  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.

How is shipping temperature determined? And how is it related to the product storage temperature?

1 Antwort
1. Technical Support
  
  vor 10 Monaten
  
  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
