Pyrantel EP Impurity D CAS 4271-96-9 chemical structure

Description

Pyrantel EP Impurity D (CAS 4271-96-9) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12N2 and a molecular weight of 112.17 g/mol.

Based on its molecular formula C6H12N2, Pyrantel EP Impurity D contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 112.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
