Abstract

Cholecalciferol Reference Standard for the Japanese Pharmacopoeia (JP RS) was prepared. The following analytical data were obtained: melting point 85.8 degrees C; UV and IR spectra were in agreement with both of the previous JP RS and USP RS of Cholecalciferol; absorptivity at 265 nm E1%lcm = 476; optical rotation [alpha]20D = + 110.1 degrees; no impurities were detected by TLC and HPLC analyses; assay 100.1% by HPLC against the USP RS. Based on the above results, the raw material was authorized as the Reference Standard of the National Institute of Hygienic Sciences.
