Hexadecane (also called cetane) is an alkane hydrocarbon with the chemical formula C16H34.
Hexadecane consists of a chain of 16 carbon atoms, with three hydrogen atoms bonded to the two end carbon atoms, and two hydrogens bonded to each of the 14 other carbon atoms.

Hexadecane is often used as a shorthand for cetane number, a measure of the combustion of diesel fuel.
Hexadecane ignites very easily under compression; for this reason, it is assigned a cetane number of 100, and serves as a reference for other fuel mixtures.

Hexadecyl radical:

Hexadecyl is an alkyl radical of carbon and hydrogen derived from hexadecane, with formula C16H33 and with mass 225.433, occurring especially in cetyl alcohol.
It confers strong hydrophobicity on molecules containing it.

Hexadecane is a component of gasoline, and is used as a solvent, organic intermediate, ignition standard for diesel fuels, and as stock for hydrocracking processes.

- Employed in industry as Adsorbents, Fuels and fuel additives.
- Also in Fabric, Textile, and Leather Products.
- Solvent, organic intermediate, ignition standard for diesel fuels.
- Fuels and Related Products.

Hexadecane was used as a solvent, a gas chromatography comparison sample, and a standard substance for the determination of diesel combustion quality.
The cetane number of diesel oil is equal to the body percentage of decabane contained in standard fuel (a mixture of cetane and a-methylnaphthalene) when the combustion quality is the same as that of the diesel under evaluation under specified working conditions.
Hexadecane is used as a gas chromatography reference substance and a fixed solution and solvent.
Hexadecane is also used in organic synthesis.
Hexadecane is use in the recovery of valuable amines by means of distillation from aqueous alkanolamine solutions, which are extensively used in the gas-processing industries.

Hexadecane, also known as cetan or CH3-[CH2]14-CH3, is a straight-chain alkane with 16 carbon atoms.
Hexadecane belongs to the class of organic compounds known as alkanes.
These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and consist entirely of hydrogen atoms and saturated carbon atoms.
Hexadecane is a hydrocarbon lipid molecule that is very hydrophobic, practically insoluble in water, and relatively neutral.
Hexadecane is an alkane taste.
Hexadecane is found in highest concentrations in black walnuts.
Hexadecane has also been detected in allspices, cucumbers, tea, orange bell peppers, and herbs and spices.
This could make hexadecane a potential biomarker for the consumption of these foods.

Hexadecane has been used as a phase change material (PCM) in the preparation of hexadecane/xGnP (exfoliated graphite nanoplatelet), a composite PCM loaded with xGnP.

Saturated aliphatic hydrocarbons, such as N-HEXADECANE-D34, may be incompatible with strong oxidizing agents like nitric acid.
Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles.
In other settings, aliphatic saturated hydrocarbons are mostly unreactive.
They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water.
