Chemical Structure

Cefepime EP Impurity G Sulfate CAS 684226-89-9 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 G Sulfate (CAS 684226-89-9) is a high-purity analytical reference standard with the molecular formula H2O4SC5H11N and a molecular weight of 183.22 g/mol.

Structurally, Cefepime EP Impurity G Sulfate (H2O4SC5H11N) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 183.22 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
