Chemical Structure
Description
Based on its molecular formula C29H31N7O2, Imatinib Impurity 3 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 509.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Imatinib Impurity 3 (CAS 938082-57-6) is a certified pharmaceutical impurity reference standard with the molecular formula C29H31N7O2 and a molecular weight of 509.60 g/mol.
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.
