Description
Heptane, high purity lab grade, listed at 99%. This is a mixed heptanes cut rather than a single-isomer product. If your method requires straight-chain n-heptane specifically – for example as a chromatographic reference solvent – check the composition below against the separate n-heptane pure grade listing before ordering.
Declared composition (from the SDS)
- Naphtha (petroleum), hydrotreated light / solvent naphtha (petroleum), light aliphatic – CAS 64742-49-0 / 426260-76-6 / 64742-89-8 – 90-100%
- Heptane, branched, cyclic and linear, and n-heptane – CAS 142-82-5 – 30-50%

Classification
Category 2 flammable liquid under 29 CFR 1910.1200, with aspiration toxicity Category 1, skin irritation Category 2 and respiratory sensitisation Category 1. Signal word: Danger. Hazard statements H225, H304, H315 and H336 are declared. The SDS notes that vapours may form an explosive mixture with air.
Container sizes
1 quart, 1 gallon, 5 gallons and 55 gallons.
Frequently asked questions
Is this straight-chain n-heptane?+
No. The SDS composition table declares hydrotreated light naphtha / light aliphatic solvent naphtha at 90-100%, with branched, cyclic and linear heptanes and n-heptane (CAS 142-82-5) at 30-50%. If your method requires a single-isomer n-heptane, use the separate n-heptane pure grade listing instead.
What are the boiling range and flash point?+
Boiling range 98.2-100 °C, melting point -90.5 °C and flash point -9 °C per the SDS. Evaporation rate is greater than 1 and autoignition is between 246 °C and 260 °C.
How soluble is it in water?+
0.002 g/L at 25 °C, with a n-octanol/water partition coefficient of 4.5, so it is effectively immiscible and will form a separate upper phase.
What are the flammability data?+
Category 2 flammable liquid, signal word Danger, with flammability limits quoted as 35 g/m3 lower and 280 g/m3 upper. The SDS notes vapours may form an explosive mixture with air and directs that heat, flame, sparks and other ignition sources be kept away.
What health hazards are declared?+
H225 highly flammable liquid and vapour, H304 may be fatal if swallowed and enters airways, H315 causes skin irritation, and H336 may cause drowsiness or dizziness. Respiratory sensitisation Category 1 is also declared.
What container sizes are available?+
1 quart, 1 gallon, 5 gallons and 55 gallons.
