Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 383.85 g/mol gives N-Nitroso Fedratinib Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Nitroso Fedratinib Impurity 2 (CAS CATO-C4X-30882) is a certified pharmaceutical impurity reference standard with the molecular formula C15H18ClN5O3S and a molecular weight of 383.85 g/mol.
Structurally, N-Nitroso Fedratinib Impurity 2 (C15H18ClN5O3S) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 383.85 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.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), N-Nitroso Fedratinib 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.
