Chemical Structure

Cefepime EP Impurity E CAS 110026-16-9 chemical structure

Description

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.

Cefepime EP Impurity E (CAS 110026-16-9) is a high-purity analytical reference standard with the molecular formula C5H11NHCl and a molecular weight of 121.61 g/mol.

Based on its molecular formula C5H11NHCl, Cefepime EP Impurity E contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 121.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
