1-Heneicosanol, or heneicosyl alcohol, is a saturated fatty alcohol with 21 carbon atoms and the molecular formula C₂₁H₄₄O. At room temperature, it is a white solid. Similar to other fatty alcohols, it is used industrially as a surfactant and lubricant.

Natural occurrence

1-Heneicosanol naturally occurs in various flowering plants, such as the tomato^[1] and napa cabbage.^[2] A 2021 study analyzing the chemical composition of cow urine through gas chromatography–mass spectrometry found that 1-heneicosanol is one of its major components.^[3]
