Compared with other compounds in its class, the molecular weight of 270.29 g/mol gives Morinidazole Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Morinidazole Impurity 37 (CAS 87008-47-7) is a certified pharmaceutical impurity reference standard with the molecular formula C11H18N4O4 and a molecular weight of 270.29 g/mol.
Based on its molecular formula C11H18N4O4, Morinidazole Impurity 37 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 270.29 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.
