Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16. 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 (the 100 point is 100% iso-octane ).
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

Theoretically 2-methylhexane also burns with a less sooty flame, emitting higher-frequency radiation; however, as heptane and 2-methylhexane differ by only one carbon atom, in terms of branching, both burn with a bright yellow flame when ignited. Compared to n-heptane, 2-methylhexane has lower melting and boiling points. 2-methylhexane is also ...
Perfluoroheptane, C 7 F 16, (usually referring to the straight chain molecule called n-perfluoroheptane) is a perfluorocarbon. [2] It is hydrophobic (water-insoluble) and oleophobic (oil-insoluble). It is used in deacidification of paper as a medium carrying powdered magnesium oxide. [3]

There's growing evidence to suggest that GLP-1 drugs, which include Ozempic's semaglutide, may be useful for treating alcohol use disorder.
The density and boiling are the lowest of the isomers of heptane. The dielectric constant is 1.915, the lowest of the heptane isomers. The critical temperature is 247.7 °C and critical pressure 28.4 atmospheres. The refractive index at 20° is 1.38233, the same as for 2,4-dimethylpentane, equal lowest for the heptane isomers.
