Chemical Structure

Cyclophosphamide Impurity 23 CAS 1361416-62-7 chemical structure

Description

Cyclophosphamide Impurity 23 (C6H15O4P) contains a phosphate ester group, a carboxylic acid 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.

Cyclophosphamide Impurity 23 (CAS 1361416-62-7) is a certified pharmaceutical impurity reference standard with the molecular formula C6H15O4P and a molecular weight of 182.15 g/mol.

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.

As a certified reference material (CRM), Cyclophosphamide Impurity 23 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.
