Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 591.42 g/mol gives Pinaverium Bromide Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Pinaverium Bromide Impurity 11 (CAS 1970218-70-2, C26H41BrNO4Br) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Pinaverium Bromide Impurity 11 (C26H41BrNO4Br) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
