Tocopherol reference standard (Control 911) of the National Institute of Hygienic Sciences

The raw material for tocopherol was tested for preparation of the "Tocopherol Reference Standard (Control 911)". Analytical data obtained were as follows: infrared spectrum, same as Tocopherol Reference Standard (Control 881); absorptivity, E1%1cm (292nm) = 75.5; thin-layer chromatography,...

Zusammenfassung:The raw material for tocopherol was tested for preparation of the "Tocopherol Reference Standard (Control 911)". Analytical data obtained were as follows: infrared spectrum, same as Tocopherol Reference Standard (Control 881); absorptivity, E1%1cm (292nm) = 75.5; thin-layer chromatography, no impurities were detected up to 50.0 micrograms; high performance liquid chromatography (HPLC), four impurities were detected; assay, 100.7% by HPLC. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Standard (Control 911).
