Special Notes
The reference substance campesterol always contains a certain percentage of its epimer dihydrobrassicasterol. The epimers cannot be separated chromatographically, however, the ratio between campesterol and dihydrobrassicasterol can be determined by the evaluation of the 13C-NMR spectra. On the certificate of analysis the absolute purity values for campesterol, dihydrobrassicasterol and total sterol content (sum of campesterol and dihydrobrassicasterol) will be given. The chromatographic and absolute purity of the reference substance shown in this quotation refers to the total sterol content.
