Chemical Structure

Glycerol Impurity 46 CAS CATO-C4X-217146 chemical structure

Description

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.

CATO supplies Glycerol Impurity 46 (CAS CATO-C4X-217146), a pharmacopoeial impurity reference standard (molecular formula C9H22O13P2, MW 400.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Glycerol Impurity 46 (C9H22O13P2) contains a carbohydrate-derived structure, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 400.21 g/mol, it falls into the moderately-high-molecular-weight range.

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.
