title: [Pyridoxine Hydrochloride Reference Standard (Control 871) of National Institute of Hygienic Sciences].
abstract: The raw material of pyridoxine hydrochloride was examined for the preparation of "Pyridoxine Hydrochloride Reference Standard". Analytical data for the sample were as follows: loss on drying is 0.01%; pH 2.94; melting point 205.2 degrees C (decomposition); IR spectrum same as the Pyridoxine Hydrochloride Reference Standard (Control 801); TLC indicates no impurities; nitrogen is 6.77% (Theoretical value 6.81%); and assay 99.5% by non-aqueous titration, 99.8% by UV spectroscopy, and 100.2% by measuring chloride ion. Based on the above results, this raw material was authorized to be Reference Standard of National Institute of Hygienic Sciences.
