General description

γ-Terpinene, volatile essential oil derived from Melaleuca alternifolia, shows antimicrobial properties against various human pathogens[1]. It is also extracted from Lippia multiflora. The antioxidant, anti-inflammatory and anti-proliferative activities of γ-terpinene is studied[2].

Application

γ-Terpinene can be used as:
  • Hydrogen precursor in the catalytic transfer hydrogenation of silyl enol ethers.[3]
  • A reference compound in the kinetic study of ozonolysis of (E)-β-farnesene.[4]
  • A hydrogen atom donor in the Cr-catalyzed radical cyclization of halo acetals.[5]

  2. 223190 gamma terpinene contains , what concentration per ml

    1 answer
    1. This product is supplied as a neat or pure liquid with a density of 0.85 g/mL and a molecular weight of 136.23 g/mol. The minimum purity is 96.5%, thus, the molarity will vary slightly from lot to lot. The molarity can range from 6.0 M (96.5%) to 6.2 M (100%). The lot-specific purity is reported on the Certificate of Analysis.
