Substance Name: beta-Tocopherol
RN: 148-03-8
UNII: 8K9365K9PX
InChIKey: WGVKWNUPNGFDFJ-DQCZWYHMSA-N

Note

  • A natural tocopherol with less antioxidant activity than alpha-tocopherol. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in GAMMA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.

Molecular Formula

  • C28-H48-O2
