Glycyrrhizic Acid Impurity 17 CAS 2919137-39-4 chemical structure

Description

CATO manufactures Glycyrrhizic Acid Impurity 17 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

As a process- or degradation-related impurity, Glycyrrhizic Acid Impurity 17 (CAS 2919137-39-4, C42H62O17) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Glycyrrhizic Acid Impurity 17 (C42H62O17) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
