General description

2-Methylbutane is a flammable and highly volatile aliphatic hydrocarbon used as a solvent in organic synthesis. It is also used to flash-freeze biological samples in conjunction with dry ice or liquid nitrogen.

Application

2-Methylbutane can be used as:      
  • A reactant to synthesize isoprene by a two-stage dehydrogenation process using chromia-alumina catalyst.     
  • A weakly polar solvent to study the intramolecular charge transfer (ICT) effect and the solvatochromic behavior of the pyrene substituted 1,3,4-oxadiazole derivatives.

Other Notes

The article number M32631-4X1L will be discontinued. Please order the single bottle M32631-1L which is physically identical with the same exact specifications.

Neuroinflammation has long been associated with the performance decline of intracortical microelectrodes (IMEs). Consequently, several strategies, including the use of anti-inflammatories, have been employed to mitigate the inflammation surrounding IMEs. However, these strategies have had limited success towards achieving a
