What is 2,2,4-Trimethylpentane? It 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 (around 10%) to increase the knock resistance of fuel.

Consistent Quality: We provide only high-quality 2,2,4-Trimethylpentane 99.8%, ensuring reliable and consistent performance for all applications.

Shipped from Manchester, UK Facility: Sourced and bottled using non-toxic, chemical-resistant containers, ensuring reliable quality for our customers.

Glass Winchester Bottle: Available in 500ml, 1L and 2.5L pack sizes. Our Glass Winchester bottles can store chemicals that may be sensitive to light due to filtering potentially harmful UV rays. Bottles are durable, versatile and perfect for storing products in the chemical, pharmaceutical and cosmetic industries.

Frequent Uses

Fuel testing
The octane rating of gasoline is measured in a test engine and is defined by comparison with the mixture of 2,2,4-trimethylpentane (iso-octane) and normal heptane that would have the same anti-knocking capability as the fuel under test. The percentage, by volume, of 2,2,4-trimethylpentane in that mixture is the octane number of the fuel. For example, gasoline with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90.

Industrial solvent
Utilised as a solvent in various manufacturing processes.

Chemical synthesis
A chemical intermediate in polymer and foam production.
