| | (1R)-(+)-ALPHA-PINENE Usage And Synthesis |
| Chemical Properties | (1R)-(+)-ALPHA-PINENE is Clear colourless liquid | | Uses | (1R)-(+)-α-Pinene is used in hydroboration reactions and the reduction of ketones. | | Uses | (+)-alpha-Pinene is employed in the preparation of chiral hydroboration reagents. It is a bronchodilator in humans. α-Pinene is an anti-inflammatory and used as a broad-spectrum antibiotic.It exhibits activity as an acetylcholinesterase inhibitor, aiding memory. It is a biosynthetic base for CB2 ligands, such as HU-308. | | Uses | (+)-α-Pinene has been used in a tolerance testing procedure to detect the genes in Marinobacter aquaeolei, for engineering a pinene tolerant Escherichia coli. | | Definition | ChEBI: The (+)-enantiomer of alpha-pinene. | | General Description | (+)-α-Pinene is a monoterpenoid compound mainly found in Pinus species. | | Flammability and Explosibility | Flammable | | Purification Methods | (1R)-(+)-ALPHA-PINENE is isomerised by heat, acids and certain solvents. It should be distilled under reduced pressure under nitrogen and stored in the dark. It has been purified via the nitrosochloride [Waterman et al. Recl Trav Chim, Pays-Bas 48 1191 1929]. For purification of optically active forms see Lynn [J Am Chem Soc 91 361 1919]. |
