Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 391.40 g/mol gives Baloxavir Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Baloxavir Impurity 4 (CAS CATO-C4X-21084) is a certified pharmaceutical impurity reference standard with the molecular formula C17H17N3O6S and a molecular weight of 391.40 g/mol.
Structurally, Baloxavir Impurity 4 (C17H17N3O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 391.40 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Impurity 4 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.
