Alpha Pinene (also known as α-terpineol or p-menth-1-en-8-ol) is a monocyclic monoterpene alcohol with the molecular formula C10H18O and a molecular weight of 154.25. It occurs naturally in the essential oils of plants such as pine, rosemary, and tea tree. In its pure form, it is a colorless, transparent, viscous liquid or low-melting-point crystal with a lilac/sugar-cane-like fragrance. It combines aromatic and alcoholic characteristics, is low-toxicity and mild, and possesses biological activities such as antibacterial, anti-inflammatory, and antioxidant properties. It is widely used in the fragrance, personal care, pharmaceutical, and industrial sectors.
