[Ergocalciferol Reference Standard (Control 871) of National Institute of Hygienic Sciences].
The Ergocalciferol Reference Standard (Control 871) for the Japanese Pharmacopoeia was prepared. The following analytical data were obtained: melting point, 115.9 degrees C; infrared spectrum, same as the Japanese Pharmacopoeia Standard "Ergocalciferol Standard (Control 851)"; absorbance, E1%1cm (265 nm) = 464.8; optical rotation, [alpha]20D = +104.7 degrees; thin-layer chromatography, same as the Japanese Pharmacopoeia Standard; high-performance liquid chromatography, contaminants were not detected; assay, 101.2%. On the basis of those results, this material was authorized as the Japanese Pharmacopoeia Standard (control 871).
