Chemical Structure
Description
As a process- or degradation-related impurity, Diosmin Impurity 8 (Mixture of Diastereomers) (CAS 108815-81-2, C27H32O14) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Diosmin Impurity 8 (Mixture of Diastereomers) (C27H32O14) 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Diosmin Impurity 8 (Mixture of Diastereomers) 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.
