Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 405.23 g/mol gives Maribavir Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Maribavir Impurity 2 (CAS CATO-C4X-30072) is a certified pharmaceutical impurity reference standard with the molecular formula C15H18Cl2N4O5 and a molecular weight of 405.23 g/mol.
Structurally, Maribavir Impurity 2 (C15H18Cl2N4O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 405.23 g/mol, it falls into the moderately-high-molecular-weight range. 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), Maribavir Impurity 2 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.
