Chemical Structure
Description
Aclidinium bromide impurity 13 (CAS CATO-C4X-132513) is a certified pharmaceutical impurity reference standard with the molecular formula C23H28NO3Br and a molecular weight of 446.38 g/mol.
The molecular framework of Aclidinium bromide impurity 13 (C23H28NO3Br) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 Aclidinium bromide 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.
