Chemical Structure

Glycerol Impurity 25 CAS 2075-06-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 252.05 g/mol gives Glycerol Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Glycerol Impurity 25 (CAS 2075-06-1), a pharmacopoeial impurity reference standard (molecular formula C3H10O9P2, MW 252.05 g/mol) used for the identification and quantification of trace impurities in APIs.

Glycerol Impurity 25 (C3H10O9P2) contains a phosphate ester group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
