Abstract:

The raw materials of d-camphor and dl-camphor were examined for the preparation of the "d-Camphor Reference Standard" and "dl-Camphor Reference Standard". Analytical data obtained were as follows: ultraviolet spectrum, lambda max = 257 nm; absorbance, E1%1cm(257 nm) = 723; infrared spectrum, 2956, 1742, 1045 cm-1; optical rotation, [alpha]20D = +42.9 degrees (d-camphor), [alpha]20D = -0.00 degrees (dl-camphor); melting point, 180 degrees C (d-camphor), 179 degrees C (dl-camphor); gas-chromatography, one impurity was detected in d-camphor and four impurities were detected in dl-camphor. Based on the above results, these raw materials were authorized to be the Reference Standards of the National Institute of Hygienic Sciences.
