Chemical Structure

Posaconazole Impurity 38 CAS CATO-C4X-120838 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 38.

CATO supplies Posaconazole Impurity 38 (CAS CATO-C4X-120838), a pharmacopoeial impurity reference standard (molecular formula C36H43F2N7O4, MW 675.77 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Posaconazole Impurity 38 (C36H43F2N7O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 675.77 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 38 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.
