General description

2,2,4-Trimethylpentane, also known as isooctane, is a high-purity hydrocarbon solvent formulated for analytical applications. Its low polarity, high volatility, and chemical inertness make it an ideal solvent for gas chromatography (GC) and sample preparation in pharmaceutical, environmental, and petrochemical laboratories.
