Chemical Structure

Olaparib Impurity 149 CAS CATO-C4X-1135149 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Olaparib Impurity 149 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Olaparib Impurity 149 (CAS CATO-C4X-1135149) is a certified pharmaceutical impurity reference standard with the molecular formula C20H20FN3O2 and a molecular weight of 353.39 g/mol.

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), Olaparib Impurity 149 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.
