Heptane Uses

Heptane (CAS NO.142-82-5) (and its many isomers) is widely used in laboratories as a totally non-polar solvent. It is ideal for transport and storage as a liquid. Heptane is used to dissolve the oil spot to show the previous presence of organic compounds on a stained paper in the grease spot test. Heptane is commercially available as the rubber cement solvent "Bestine" and the outdoor stove fuel "Powerfuel" by Primus.

HazardClass: 3
PackingGroup: II
Poison by intravenous route. Mildly toxic by inhalation. Human systemic effects by inhalation: hallucinations. Narcotic in high concentrations. A volatile, flammable liquid when exposed to heat or flame. Can react vigorously with oxidizing materials. Moderately explosive when exposed to heat or flame. Violent reaction with phosphorus + chlorine. To fight fire, use foam, CO₂, dry chemical. When heated to decomposition it emits acrid smoke and fumes.
