Isooctane CAS 540-84-1

2,2,4-trimethylpentane is commonly known as isooctane (the one with a methyl group at the 2nd position of the main chain is called "iso-octane", and the one with two methyl groups at the 2nd position is called "neo-octane". However, out of habit, 2,2,4-trimethylpentane is still called "iso-octane"), which is an isomer of octane....
