Chemical Structure
Description
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.
As a process- or degradation-related impurity, Peramivir Impurity 12 HCl (CAS 229613-83-6, C7H11NO2HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Peramivir Impurity 12 HCl (C7H11NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
