General description

α-Pinene is a chemical constituent of essential oil extracted from the stem of Canarium tramdenanum.
It reacts with ozone in the air to form oxygenated products that can further react to form secondary organic aerosols (SOA).

Application

α-Pinene was used as standard in headspace solid-phase microextraction-gas chromatographic analysis of volatile compounds in virgin olive oils. It was used in the synthesis of cesium-doped heteropolyacid having potential application in biodiesel synthesis.
