Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 698.62 g/mol gives Troxerutin Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Troxerutin Impurity 2 (CAS 13190-91-5), a pharmacopoeial impurity reference standard (molecular formula C31H38O18, MW 698.62 g/mol) used for the identification and quantification of trace impurities in APIs.
Troxerutin Impurity 2 (C31H38O18) 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.
CATO manufactures Troxerutin Impurity 2 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.
