N‑Heptane
N‑Heptane is a clear, volatile, and highly flammable straight‑chain alkane with the chemical formula C7H16. It has a faint petroleum‑like odor and, as a saturated hydrocarbon, is commonly used as a non‑polar solvent, a laboratory reagent, in paints and coatings, and as the zero‑point standard for gasoline octane rating tests.
Key Details:
Chemical Formula: C7H16 (also written as H3C(CH2)5CH3)
Description: Colorless, volatile liquid that is insoluble in water but miscible with many organic solvents. It has a boiling point of approximately 98°C.
Common Uses:
- Solvent: Used as a non‑polar solvent in laboratories (HPLC, spectrophotometry) and in industrial applications for extracting oils and fats.
- Fuel Standard: Serves as the zero‑point reference on the octane rating scale (0% iso‑octane, 100% n‑heptane).
- Industry: Used in rubber cement, paints, coatings, and pharmaceutical manufacturing.
Safety: Highly flammable liquid and vapor. Exposure may cause central nervous system (CNS) depression and skin irritation.
N‑Heptane is also frequently used in fire research and as a component in, or a precursor for, high‑performance fuels.
