Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 386.74 g/mol gives Lodoxamide lmpurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lodoxamide lmpurity 15 (CAS 67605-91-8) is a certified pharmaceutical impurity reference standard with the molecular formula C15H15ClN2O8 and a molecular weight of 386.74 g/mol.
Lodoxamide lmpurity 15 (C15H15ClN2O8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
