 |  | 3,3-Dimethylpentane Usage And Synthesis |  
 | Chemical Properties | clear colorless liquid |  | Physical properties | Colorless, mobile liquid with an odor resembling heptane or gasoline. Evaporates when spilled
forming combustible vapors. |  | Uses | 3,3-Dimethylpentane Is used in organic synthesis & as gasoline component, as Pharmaceutical intermediates. It was used in the development and evaluation of the epiocular-eye irritation test. |  | General Description | 3,3-Dimethylpentane isomerizes via a methyl shift mechanism on oxygen-exposed tungsten carbides. |  | Environmental fate | Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. 3,3-
Dimethylbutane will not hydrolyze because it has no hydrolyzable functional group. |
