Glycyrrhizic Acid Impurity 34 CAS CATO-C4X-253734

Description

The occurrence of Glycyrrhizic Acid Impurity 34 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 34 (CAS CATO-C4X-253734) is a certified pharmaceutical impurity reference standard with the molecular formula C44H66O16 and a molecular weight of 850.99 g/mol.

Structurally, Glycyrrhizic Acid Impurity 34 (C44H66O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 850.99 g/mol, it falls into the high-molecular-weight range. 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.
