Chemical Structure

Glycerol Impurity 42 CAS 25664-08-8 chemical structure

Description

Based on its molecular formula C3H7O5P, Glycerol Impurity 42 contains a phosphate ester group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Glycerol Impurity 42 (CAS 25664-08-8) is a certified pharmaceutical impurity reference standard with the molecular formula C3H7O5P and a molecular weight of 154.06 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.
