It belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons with, they have the general formula CH3-[CH2]22-CH3, and consist entirely of hydrogen atoms and saturated carbon atoms. Tetracosane is a hydrocarbon lipid molecule. Tetracosane is a colourless and waxy crystal, that is very hydrophobic, practically insoluble in water, and relatively neutral. Tetracosane has been found in lindens, citrus, sunflowers, allspices, and papaya. This could make tetracosane a potential biomarker for the consumption of these foods. As a volatile oil component, tetracosane has been found in the essential oils from plants, such as dill (PMID: 25154406).
