Chemical Structure

Ascorbic Acid Impurity C CAS 16533-48-5 chemical structure

Description

The molecular framework of Ascorbic Acid Impurity C (C6H10O7) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a process- or degradation-related impurity, Ascorbic Acid Impurity C (CAS 16533-48-5, C6H10O7) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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), Ascorbic Acid Impurity C 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.
