[Pyridoxine hydrochloride reference standard (Control 911) of the National Institute of Hygienic Sciences].
The raw material of pyridoxine hydrochloride was examined for preparation of the "Pyridoxine Hydrochloride Reference Standard". Analytical data obtained were as follows: loss on drying, 0.00%; pH, 2.87; melting point, 204.6 degrees C (decomposition); infrared spectrum, same as Pyridoxine Hydrochloride Reference Standard (Control 879); thin-layer chromatography, nonimpurities were detected; assay, 100.0% by non-aqueous titration and 100.0% by UV spectrophotometry. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Standard (Control 911).
