2,2,4-Trimethylpentane, Isooctane, 99.0+%, 50ml CAS Number: 540-84-1 Linenear Formula: (CH3)2CHCH2C(CH3)3 Molecular Weight: 114.23 2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH3)3CCH2CH(CH3)2. It is one of several isomers of octane (C8H18). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane). It is an important component of gasoline, frequently used in relatively large proportions to increase the knock resistance of the fuel. Strictly speaking, if the standard meaning of ‘iso’ is followed, the name isooctane should be reserved for the isomer 2-methylpeptane.  However, 2,2,4-trimethylpentane is by far the most important isomer of octane and so, historically, it has ended up with this name.
