Chemical Structure

Ornidazole Impurity 113 CAS CATO-C4X-1331113 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ornidazole Impurity 113.

CATO supplies Ornidazole Impurity 113 (CAS CATO-C4X-1331113), a pharmacopoeial impurity reference standard (molecular formula C7H9ClN3Na2O6P, MW 343.57 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ornidazole Impurity 113 (C7H9ClN3Na2O6P) contains a salt form, a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 343.57 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
