Chemical Structure

Ascorbate Acid EP Impurity C CAS 342385-52-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 212.15 g/mol gives Ascorbate Acid EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ascorbate Acid EP Impurity C (CAS 342385-52-8), a pharmacopoeial impurity reference standard (molecular formula C6H10O7H2O, MW 212.15 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ascorbate Acid EP Impurity C (C6H10O7H2O) 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
