Chemical Structure

Posaconazole Impurity 151 CAS 17392-83-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Posaconazole Impurity 151.

CATO supplies Posaconazole Impurity 151 (CAS 17392-83-5), a pharmacopoeial impurity reference standard (molecular formula C4H8O3, MW 104.10 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Posaconazole Impurity 151 (C4H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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 151 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.
