Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Mifepristone Impurity 13.
As a process- or degradation-related impurity, Mifepristone Impurity 13 (CAS 84371-57-3, C23H30O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Mifepristone Impurity 13 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Mifepristone Impurity 13 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.
