Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 394.40 g/mol gives Olaparib Impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Olaparib Impurity 90 (CAS CATO-C4X-113590), a pharmacopoeial impurity reference standard (molecular formula C21H19FN4O3, MW 394.40 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H19FN4O3, Olaparib Impurity 90 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 394.40 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
