p-Menthane is a hydrocarbon with the formula (CH₃)₂CHC₆H₁₀CH₃. It is the product of the hydrogenation or hydrogenolysis of various terpenoids, including p-cymene, terpinolenes, phellandrene, and limonene. It is a colorless liquid with a fragrant fennel-like odor. It occurs naturally, especially in exudates of Eucalyptus fruits.
