(+)-2-Carene
(+)-2-Carene (CAS 4497-92-1; C10H16; molar mass 136.23 g/mol) is a chiral bicyclic monoterpene supplied by Tech Serve Solutions at 97% assay. A volatile, optically active liquid ([alpha]D +90 degrees), it is used principally as a chiral building block in asymmetric synthesis and terpene chemistry, and as an intermediate in fragrance and flavour work. It is a flammable liquid (flash point ~38 degrees C) that requires handling away from ignition sources.
