Chemical Structure

All-Rac-Α-Tocopherol EP Impurity C CAS 90510-39-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 444.73 g/mol gives All-Rac-Α-Tocopherol EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, All-Rac-Α-Tocopherol EP Impurity C (CAS 90510-39-7, C30H52O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

All-Rac-Α-Tocopherol EP Impurity C (C30H52O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
