Hexadecane (also called cetane) is an alkane hydrocarbon with the chemical formula C16H34. Hexadecane consists of a chain of 16 , with three bonded to the two end carbon atoms, and two hydrogens bonded to each of the 14 other carbon atoms. Isohexadecane is a branch chained isomer of hexadecane.
Cetane number
Cetane is often used as a shorthand for
cetane number, a measure of the combustion of
diesel fuel.
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.
Hexadecyl radical
Hexadecyl, or cetyl, is an
alkyl radical of
carbon and
hydrogen derived from hexadecane, with formula C
16H
33 and with mass 225.433,
occurring especially in
cetyl alcohol.
It confers strong hydrophobicity on molecules containing it.
modified with hexadecyl and polyethylene glycol has increased
liposolubility and
PEGylation, and is proposed to useful in
chemotherapy, specifically non-small-cell lung cancer.
Hexadecyl was used from 1982 for radiolabelling,
Hexadecyl platelet-activating factor has profound effects on the lung,
