Chemical Structure

Baloxavir Marboxil Impurity 216 CAS CATO-C4X-2108216 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 278.27 g/mol gives Baloxavir Marboxil Impurity 216 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Baloxavir Marboxil Impurity 216 (CAS CATO-C4X-2108216, C14H8F2O2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, Baloxavir Marboxil Impurity 216 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Baloxavir Marboxil Impurity 216 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
