Heptane,99%, CAS No. 142-82-5
Straight-Chain Alkane
Heptane or n-heptane is the straight-chain alkane with the chemical formula H₃C(CH₂)₅CH₃ or C₇H₁₆, and is one of the main components of gasoline. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale. Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline dispensed globally.

Structure:

Density: 0.68 g/cm³
Boiling point: 209.16°F (98.42°C)
Chemical formula: C₇H₁₆
Average Molar mass: 100.21 g/mol
