Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.23 g/mol gives Levosimendan Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Levosimendan Impurity 5 (CAS CATO-C4X-13085) is a certified pharmaceutical impurity reference standard with the molecular formula C13H11NO7 and a molecular weight of 293.23 g/mol.
Levosimendan Impurity 5 (C13H11NO7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
