Lesinurad Impurity 4 CAS 1547295-10-2 chemical structure

Description

As a certified reference material (CRM), Lesinurad Impurity 4 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.

Lesinurad Impurity 4 (CAS 1547295-10-2) is a certified pharmaceutical impurity reference standard with the molecular formula C14H15N3S and a molecular weight of 257.35 g/mol.

Lesinurad Impurity 4 (C14H15N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
