β-Tocopherol (Standard) is the standard substance of β-Tocopherol, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. β-Tocopherol, an analogue of vitamin E, showcases antioxidant properties, and can impede tyrosinase activity and melanin synthesis. Additionally, it prevents the inhibition of cell growth and protein kinase C (PKC) activity that d-alpha-tocopherol causes.
