Description
As a certified reference material (CRM), Carbocisteine Impurity 63 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.
CATO supplies Carbocisteine Impurity 63 (CAS CATO-C4X-201063), a pharmacopoeial impurity reference standard (molecular formula C19H26O13, MW 462.40 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Carbocisteine Impurity 63 (C19H26O13) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
