Isohexane

Isohexane is a common name for 2-methylpentane, an isomer of hexane (C6H14). It is a branched alkane and one of several structural isomers of hexane.

Chemically, it consists of a six-carbon chain with a single methyl substituent on the second carbon, giving a branched geometry that influences its boiling point and volatility.

Production and occurrence: Isohexane is produced during the refining of crude oil and natural gas condensates and is a component of gasoline and other hydrocarbon solvents.

Physical properties: It is a colorless, low-viscosity liquid that is highly flammable. It is insoluble in water but miscible with most organic solvents. It has a relatively low boiling point compared with many liquids, contributing to its volatility.

Uses: Isohexane is used as a solvent in paints, coatings, cleaning agents, and as a reagent in organic synthesis. It is also found in gasoline as a component that contributes to volatility and energy content.

Safety: Isohexane is flammable and can cause dizziness or drowsiness if inhaled in large amounts. It should be handled in well-ventilated areas, away from ignition sources, with appropriate storage and personal protective equipment.

Related compounds: Other hexane isomers include n-hexane, 3-methylpentane, 2,2-dimethylbutane (neohexane), and 2,3-dimethylbutane.
