Description
Pinaverium impurity 26 (CAS CATO-C4X-246726) is a certified pharmaceutical impurity reference standard with the molecular formula C18H20Br2O5 and a molecular weight of 476.16 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, Pinaverium impurity 26 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 476.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 certified reference material (CRM), Pinaverium impurity 26 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
