Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 420.89 g/mol gives Dalilesen Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dalilesen Impurity 8 (CAS 1505484-72-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H21ClN6O and a molecular weight of 420.89 g/mol.
The molecular framework of Dalilesen Impurity 8 (C22H21ClN6O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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 Dalilesen Impurity 8 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.
