Chemical Structure

Glycerol Impurity 47 CAS CATO-C4X-217147 chemical structure

Description

The occurrence of Glycerol Impurity 47 is closely related to a carbohydrate-derived structure, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Glycerol Impurity 47 (CAS CATO-C4X-217147) is a certified pharmaceutical impurity reference standard with the molecular formula C9H21O10P and a molecular weight of 320.23 g/mol.

Structurally, Glycerol Impurity 47 (C9H21O10P) contains a carbohydrate-derived structure, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 320.23 g/mol, it falls into the moderately-high-molecular-weight range.

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), Glycerol Impurity 47 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.
