Posaconazole Impurity 269 CAS CATO-C4X-1208269

Description

The occurrence of Posaconazole Impurity 269 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Posaconazole Impurity 269 (CAS CATO-C4X-1208269) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18O2 and a molecular weight of 194.27 g/mol.

The molecular framework of Posaconazole Impurity 269 (C12H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Posaconazole Impurity 269 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.
