Chemical Structure
Description
Glycyrrhizic Acid Impurity 8 (CAS CATO-C4X-25378) is a certified pharmaceutical impurity reference standard with the molecular formula C44H66O16 and a molecular weight of 850.99 g/mol.
The molecular framework of Glycyrrhizic Acid Impurity 8 (C44H66O16) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
