Ropinirole Impurity 3 HCl CAS 1076199-41-1

Description

Compared with other compounds in its class, the molecular weight of 312.84 g/mol gives Ropinirole Impurity 3 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Ropinirole Impurity 3 HCl (CAS 1076199-41-1, C16H24N2O2HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ropinirole Impurity 3 HCl (C16H24N2O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
