Azacitidine Impurity 89 CAS 69350-76-1

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.

CATO supplies Azacitidine Impurity 89 (CAS 69350-76-1), a pharmacopoeial impurity reference standard (molecular formula C27H24O8, MW 476.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Azacitidine Impurity 89 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 476.47 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 Azacitidine Impurity 89 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.
