Diazoxide Impurity 13 CAS CATO-C4X-195213

Description

Compared with other compounds in its class, the molecular weight of 663.90 g/mol gives Diazoxide Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Diazoxide Impurity 13 (CAS CATO-C4X-195213), a pharmacopoeial impurity reference standard (molecular formula C18H18Cl3N6O7PS3, MW 663.90 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Diazoxide Impurity 13 (C18H18Cl3N6O7PS3) is characterized by a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Diazoxide Impurity 13 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.
