title: [Cholecalciferol Reference Standard (Control 871) of National Institute of Hygienic Sciences].
abstract: Cholecalciferol Reference Standard (Control 871) for the Japanese Pharmacopoeia was prepared. The following analytical data were obtained: melting point, 86.3 degrees C; infrared spectrum, same as the Japanese Pharmacopoeia Standard "Cholecalciferol Standard (Control 851)"; absorbance, E1%1cm (265 nm) = 474.5; optical rotation, [alpha]20D = + 110.0 degrees; thinlayer chromatography, same as the Japanese Pharmacopoeia Standard; highperformance liquid chromatography, contaminants were not detected; assay, 100.7%. On the basis of those results, this material was authorized as the Japanese Pharmacopoeia Standard (control 871).
