Relugolix Impurity 166 CAS CATO-C4X-2429166

Description

Compared with other compounds in its class, the molecular weight of 626.63 g/mol gives Relugolix Impurity 166 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Relugolix Impurity 166 (CAS CATO-C4X-2429166), a pharmacopoeial impurity reference standard (molecular formula C29H28F2N6O6S, MW 626.63 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Relugolix Impurity 166 (C29H28F2N6O6S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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), Relugolix Impurity 166 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.
