Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 174.13 g/mol gives Olaparib Impurity 103 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Olaparib Impurity 103 (CAS 2691818-05-8), a pharmacopoeial impurity reference standard (molecular formula C9H3FN2O, MW 174.13 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Olaparib Impurity 103 (C9H3FN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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 174.13 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.
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.
CATO manufactures Olaparib Impurity 103 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
