Hexadecane (also called cetane) is an

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.

Cetane number

Main article: Cetane number

Cetane is often used as a shorthand for cetane number, a measure of the combustion of diesel fuel.[9] Cetane 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.[10]

Hexadecyl radical

Hexadecyl is an

liposolubility and PEGylation, proposed to useful in chemotherapy, specifically non-small-cell lung cancer.[14]

Hexadecyl was used from 1982 for

hydrogels,[17]
and for positron emission tomography.[18]

Hexadecyl

plasmalogens.[20]
