What is the difference between heptane and n-heptane?
There are many different types of heptanes, which are mixtures that contain 25% or less of n-heptane. N-heptane is the pure form of heptane, that is often used as an industrial degreaser as well as in the petroleum industry. N-heptane is a very potent chemical when compared to other heptanes so it is important to understand the difference between heptane and n-heptane. N-heptane is a clear, liquid that has a strong gasoline like scent. N-heptane must be handled with care and supplied in a responsible manner.

| Heptane | n-Heptane | |
|---|---|---|
| Composition | Mixture of all 9 structural isomers of C7H16 | Pure, single isomer of C7H16 (straight-chain structure) |
| Purity | Low to moderate (typically 50-90% total C7H16, with isomers) | High (often >99% pure in commercial grades) |
| Physical Properties | Variable (e.g., boiling point 90-100°C; density 0.68-0.70 g/cm³) | Fixed (boiling point 98.4°C; density 0.684 g/cm³ at 20°C) |
| Key Use Case | General-purpose solvent (degreasing, cleaning, paint thinning) | Precision applications (octane rating calibration, lab research) |
| Octane Rating Relevance | Not a standard (mixed isomers have variable octane numbers) | Primary standard (defined as 0 octane rating for gasoline testing) |
| Contamination Risk | May contain impurities or residual branched isomers | Minimal (high purity reduces contamination in sensitive processes) |
