Description
CATO manufactures Glycyrrhizic Acid Impurity 11 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.
CATO supplies Glycyrrhizic Acid Impurity 11 (CAS CATO-C4X-253711), a pharmacopoeial impurity reference standard (molecular formula C48H74O16, MW 907.09 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Glycyrrhizic Acid Impurity 11 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 907.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
