General description
2-methylpropene is used to synthesize S-(+)-2,2-Dimethylcyclopropane carboxylic acid via asymmetric cyclopropanation reaction.
Application
2-Methylpropene can be used in the following reactions:
- Asymmetric synthesis of S-(+)-2,2-dimethylcyclopropane carboxylic acid, a key building block for the synthesis of cilastatin.
- Alkylation of p-xylene to form t-butyl-p-xylene catalyzed by a heteropolyacid.
- Synthesis of poly(2-methylpropene) or polyisobutene.
Packaging
Supplied in a Sure/Pac™ cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.
Compatible with the following:
