설명

일반 설명

2-Methylbutane (Isopentane) is a branched chain alkane.[1] It undergoes bromination at 75°C to afford 2-bromo-2-methyl butane.[2] Its Raman spectra in vapor and solid phases at low temperatures (-196°C) have been investigated.[3]

애플리케이션

2-Methylbutane may be used in the following studies:

• As starting reagent for the synthesis of isoprene.[4]
• Preparation of C₅ and C₆ alkyl nitrates.[5]
