Chemical Structure
Description
Based on its molecular formula C15H12BrN3O, Lesinurad Impurity 12 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Lesinurad Impurity 12 (CAS CATO-C4X-147812) is a certified pharmaceutical impurity reference standard with the molecular formula C15H12BrN3O and a molecular weight of 330.18 g/mol.
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), Lesinurad Impurity 12 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.
