Description

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.
