Description
CATO supplies Iguratimod Impurity 104 (CAS CATO-C4X-1826104), a pharmacopoeial impurity reference standard (molecular formula C12H11NO2, MW 201.22 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Iguratimod Impurity 104 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 104 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.
