Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.75 g/mol gives Nerandomilast Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Nerandomilast Impurity 34 (CAS CATO-C4X-347334) is a certified pharmaceutical impurity reference standard with the molecular formula C11H12ClN3O2S and a molecular weight of 285.75 g/mol.
Structurally, Nerandomilast Impurity 34 (C11H12ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 285.75 g/mol, it falls into the medium-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), Nerandomilast Impurity 34 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.
