(-)-α-Pinene(CAS: 7785-26-4)

(-)-α-Pinene is a cyclic monoterpene with a strong pine scent. It is a colorless to slightly yellowish liquid with a molecular weight of 136.23 g/mol. The compound has a specific gravity of 0.8662 and is soluble in ethanol, ether, and other organic solvents. It is moderately reactive, especially with bases and oxidizing agents.

(-)-α-Pinene is commonly synthesized via catalytic hydrogenation of d-limonene with a rhodium-based catalyst. The stereoselective hydrogenation yields high purity (-)-α-pinene with good yield and selectivity. Alternative methods include bioconversion processes using microorganisms capable of producing α-pinene.

(-)-α-Pinene is widely used in the fragrance and flavor industry, as well as in the pharmaceutical, polymer, and sensor industries. It is also utilized in the production of adhesives, coatings, and as a component in certain semiconductors and electronic materials.

When handling (-)-α-Pinene, it is important to use appropriate personal protective equipment (PPE), such as gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood. Store the compound in a cool, dry place away from heat sources. Follow standard safety procedures and have a Material Safety Data Sheet (MSDS) readily available. In case of spill, avoid inhalation of the fumes and use appropriate spill cleanup methods as outlined in the MSDS.
