Chemical Structure

Rivaroxaban Impurity N4 CAS 1252018-21-5 chemical structure

Description

As a certified reference material (CRM), Rivaroxaban Impurity N4 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.

Rivaroxaban Impurity N4 (CAS 1252018-21-5) is a certified pharmaceutical impurity reference standard with the molecular formula C13H17ClN2O3 and a molecular weight of 284.74 g/mol.

Structurally, Rivaroxaban Impurity N4 (C13H17ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 284.74 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.
