Compared with other compounds in its class, the molecular weight of 132.16 g/mol gives Rasagiline Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Rasagiline Impurity 8 (CAS 83-33-0), a pharmacopoeial impurity reference standard (molecular formula C9H8O, MW 132.16 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C9H8O, Rasagiline Impurity 8 contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 132.16 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).
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), Rasagiline Impurity 8 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.
