Terpinen-4-ol is an isomer of terpineol with the chemical formula C₁₀H₁₈O. A primary constituent of tea tree oil,^[1] it is obtained as an extract from the leaves, branches, and bark of Melaleuca alternifolia Cheel.^[2]^[3]^[4] Despite considerable basic and preliminary clinical research of terpinen-4-ol and tea tree oil, its biological properties and potential for clinical uses have not been established as of 2019.^[2] It may be a factor in the contact dermatitis of tea tree oil when used topically.^[2]^[3]

Terpinen-4-ol occurs in Juniperus communis and is thought to be the reason why this wood is highly resistant to rot. ^{[citation needed]}

Synthesis

Terpinen-4-ol can be synthesized from terpinolene (1) by photooxidation, reduction of the resulting hydroperoxide (2), and selective hydrogenation of the terminal double bond in 3.
