Applications

2-Methyl-2-butene is used to prepare 3-Brom-2.3-dimethyl-1.1-dicyan-butan in the presence of 2,2'-azobis-(2,4-dimethyl-4-methoxyvaleronitrile) as a catalyst. It is used as a precursor for peroxyacetyl nitrate for the calibration purposes.

Notes

0.66Store in a cool place. Incompatible with acids and oxidizing agents. Avoid conditions like heat, flames and sparks.
