[Tocopherol acetate reference standard (Control 911) of the National Institute of Hygienic Sciences].
The raw material for tocopherol acetate was tested for preparation of the "Tocopherol Acetate Reference Standard (Control 911)". Analytical data obtained were as follows: infrared spectrum, same as Tocopherol Acetate Reference Standard (Control 881); absorptivity, E1cm1% (284nm) = 43.5; thin-layer chromatography, no impurities were detected up to 50.0 micrograms; high performance liquid chromatography (HPLC), two impurities were detected; assay, 100.3% by HPLC. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Standard (Control 911).
