Chemical Structure

Policresulen Impurity 15 CAS CATO-C4X-198015 chemical structure

Description

Structurally, Policresulen Impurity 15 (C7H8O10S3) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 348.33 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).

Policresulen Impurity 15 (CAS CATO-C4X-198015) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8O10S3 and a molecular weight of 348.33 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.

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.
