Description
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.
Posaconazole Impurity 87 (CAS CATO-C4X-120887) is a certified pharmaceutical impurity reference standard with the molecular formula C29H37N5O3 and a molecular weight of 503.64 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Posaconazole Impurity 87 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 503.64 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).
CATO manufactures Posaconazole Impurity 87 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.
