Chemical Structure

Azacitidine Impurity 34 CAS CATO-C4X-138834 chemical structure

Description

As a certified reference material (CRM), Azacitidine Impurity 34 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Azacitidine Impurity 34 (CAS CATO-C4X-138834) is a certified pharmaceutical impurity reference standard with the molecular formula C8H17N3O5 and a molecular weight of 235.24 g/mol.

Azacitidine Impurity 34 (C8H17N3O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
