摘要

为制备《盐酸硫胺素参考标准品(对照品931)》,对盐酸硫胺素原料进行了检测。得到的分析数据如下:熔点242.7℃(分解);红外光谱,与JP盐酸硫胺素标准品相同;薄层色谱法,检出杂质1个;高效液相色谱法检测到微量杂质;紫外分光光度法100.4%,高效液相色谱法100.0%。根据上述结果,该原料被批准为JP盐酸硫胺素参考标准品(Control 931)。

[The Thiamine Hydrochloride Reference Standard (Control 931) of the National Institute of Health Sciences].

Raw thiamine hydrochloride material was tested for preparation of the "Thiamine Hydrochloride Reference Standard (Control 931)". Analytical data obtained were as follows: melting point, 242.7 degrees C (decomposition); infrared spectrum, the same as that of the JP Thiamine Hydrochloride Reference Standard; thin-layer chromatography, one impurity was detected; high-performance liquid chromatography (HPLC), a trace amount of one impurity was detected; assay results, 100.4% by UV spectrophotometry and 100.0% by HPLC, respectively. Based on the above findings, the raw material was authorized as the JP Thiamine Hydrochloride Reference Standard (Control 931).
