Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.25 g/mol gives N-Nitroso Metronidazole Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Nitroso Metronidazole Impurity 34 (CAS CATO-C4X-140534) is a certified pharmaceutical impurity reference standard with the molecular formula C9H15N5O5 and a molecular weight of 273.25 g/mol.
Based on its molecular formula C9H15N5O5, N-Nitroso Metronidazole Impurity 34 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
