Abstract
Raw alprostajil material was examined for preparation of the "Alprostajil Reference Standard (Control 921)". Analytical data obtained were as follows: infrared spectrum, the same as that of the USP Alprostajil Reference Standard; thin-layer chromatography, no impurities were detected up to 20 micro g; high-performance liquid chromatography (HPLC), no impurities were detected; assay result, 99.6% by HPLC. Based on the above findings, this raw material was authorized as the NIHS Alprostajil Reference Standard (Control 921).
