Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.35 g/mol gives Imatinib Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Imatinib Impurity 25 (CAS CATO-C4X-106825) is a certified pharmaceutical impurity reference standard with the molecular formula C17H17N5 and a molecular weight of 291.35 g/mol.
Structurally, Imatinib Impurity 25 (C17H17N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 291.35 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Imatinib Impurity 25 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.
