[dl-Camphor Reference Standard (Control 961) of National Institute of Health Sciences].
The raw material of dl-camphor was examined for the preparation of the "dl-Camphor Reference Standard (Control 961)" of National Institute of Health Sciences. Analytical data obtained are as follows: UV spectrum, lambda max = 290 nm; IR spectrum, the same as that of the present JP Camphor Reference Standard (Control 953); melting point, 179.1 degrees C; purity test by gas-chromatography (GC), three kinds of impurities were detected; assay by GC, 99.8%. Based on the above results, the candidate raw material was authorized as the dl-Camphor Reference standard (Control 961) National Institute of Health Sciences (Japanese Pharmacopoeia).
