Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 157.60 g/mol gives Iguratimod Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Iguratimod Impurity 10 (CAS 2401-24-3) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8ClNO and a molecular weight of 157.60 g/mol.
Iguratimod Impurity 10 (C7H8ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Iguratimod Impurity 10 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.
