Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 326.26 g/mol gives Diacerein EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diacerein EP Impurity E (CAS 875535-36-7) is a certified pharmaceutical impurity reference standard with the molecular formula C17H10O7 and a molecular weight of 326.26 g/mol.
The molecular framework of Diacerein EP Impurity E (C17H10O7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Diacerein EP Impurity E 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.
