Baloxavir Marboxil Impurity 157 CAS CATO-C4X-2108157

Description

The occurrence of Baloxavir Marboxil Impurity 157 is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Baloxavir Marboxil Impurity 157 (CAS CATO-C4X-2108157), a pharmacopoeial impurity reference standard (molecular formula C30H31F2N3O6S, MW 599.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C30H31F2N3O6S, Baloxavir Marboxil Impurity 157 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 599.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Baloxavir Marboxil Impurity 157 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.
