Chemical Structure

Glycyrrhizic Acid Impurity 15 CAS 30430-55-8 chemical structure

Description

The occurrence of Glycyrrhizic Acid Impurity 15 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Glycyrrhizic Acid Impurity 15 (CAS 30430-55-8) is a certified pharmaceutical impurity reference standard with the molecular formula C45H68O16 and a molecular weight of 865.01 g/mol.

The molecular framework of Glycyrrhizic Acid Impurity 15 (C45H68O16) 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.
