摘要
为编制“dl-樟脑标准品”，对dl-樟脑原料进行了考察。得到的分析数据如下:紫外光谱，λ max = 290 nm;红外光谱，与现行JP樟脑参考标准相同;熔点:179.6℃;气相色谱(GC)纯度检测，检测出3种杂质;气相色谱法，99.0%。根据上述结果，该候选原料被批准为JP参考标准(Control 951)。
[dl-Camphor Reference Standard (Control 951) of the National Institute of Health Sciences].
The raw material of dl-camphor was examined for the preparation of the "dl-Camphor Reference Standard". Analytical data obtained are as follows: ultraviolet spectrum, lambda max = 290 nm; infrared spectrum, the same as that of the present JP Camphor Reference Standard; melting point, 179.6 degrees C; purity test by gas-chromatography (GC), three kinds of impurities were detected; assay by GC, 99.0%. Based on the above results, the candidate raw material was authorized as the JP Reference Standard (Control 951).
