Chemical Structure

Glycerol Impurity 17 CAS 110972-48-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 194.06 g/mol gives Glycerol Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Glycerol Impurity 17 (CAS 110972-48-0), a pharmacopoeial impurity reference standard (molecular formula C3H8O6PNa, MW 194.06 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Glycerol Impurity 17 (C3H8O6PNa) contains a phosphate ester group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 194.06 g/mol, it falls into the medium-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 17 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.
