Chemical Structure

Azacitidine Impurity 88 CAS 16491-66-0 chemical structure

Description

As a process- or degradation-related impurity, Azacitidine Impurity 88 (CAS 16491-66-0, C6H10N4O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Azacitidine Impurity 88 (C6H10N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Azacitidine Impurity 88 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.
