Iguratimod Impurity 149 CAS CATO-C4X-1826149

Description

Compared with other compounds in its class, the molecular weight of 350.39 g/mol gives Iguratimod Impurity 149 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Iguratimod Impurity 149 (CAS CATO-C4X-1826149) is a certified pharmaceutical impurity reference standard with the molecular formula C16H18N2O5S and a molecular weight of 350.39 g/mol.

Based on its molecular formula C16H18N2O5S, Iguratimod Impurity 149 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.39 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).

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.

CATO manufactures Iguratimod Impurity 149 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
